For many people, IVF begins with a sudden shift. Trying to conceive used to be private. Now it involves consent forms, pharmacy deliveries, medication in the fridge and ultrasound appointments booked before breakfast. Each word on the clinic leaflets makes sense on its own. The order things happen in, and what each week will ask of you, often doesn't.

This guide walks through the IVF process step by step, from first consultation to pregnancy test. For each phase it covers what happens, how it may feel physically and emotionally, the realistic time commitment and the questions worth asking your clinic.

Clinics use different protocols, and every body responds differently. Treat this as a map rather than a script. Your fertility team's instructions always come first.

IVF at a glance: what one cycle looks like

In IVF (in vitro fertilisation), eggs are collected from the ovaries and fertilised with sperm in a lab. An embryo is then transferred into the uterus. Any suitable extra embryos may be frozen for later.

Most IVF journeys follow these seven phases:

  1. First consultation and fertility tests
  2. Protocol and medication preparation
  3. Ovarian stimulation and monitoring
  4. Trigger shot and egg retrieval
  5. Fertilisation and embryo development in the lab
  6. Fresh or frozen embryo transfer
  7. The two-week wait and pregnancy test

The active treatment cycle often takes around four to six weeks. The whole journey usually takes longer, because tests, referrals, waiting lists, funding approval and frozen transfers all add time.

An illustrative timeline (example only, yours will vary):

  • Early in your cycle: baseline scan, and stimulation injections start
  • Roughly days 1 to 10 of stimulation: daily injections and several monitoring scans
  • When follicles are ready: trigger shot
  • About a day and a half later: egg retrieval
  • Five days after retrieval: blastocyst transfer
  • Around nine to eleven days after transfer: the clinic's pregnancy test

One more detail matters. Clinics and health systems define "one cycle" differently. It might mean a single egg collection, or it might include a fresh transfer and later frozen transfers. That affects funding and cost, so ask exactly what is included.

The IVF process step by step, phase by phase

Phase 1: First consultation and fertility tests

Your first appointment is mainly about gathering facts. Expect questions about your cycle, any previous pregnancies or losses, your medical history, medications, lifestyle and how long you have been trying. If you have a partner, their health history matters too.

Common tests include:

  • hormone blood tests
  • a pelvic ultrasound
  • an ovarian reserve assessment, such as AMH and an antral follicle count

These estimate how many eggs might respond to stimulation. They do not measure egg quality, and they cannot predict your outcome on their own.

Depending on your situation, you may also have:

  • a semen analysis, or donor screening
  • infection screening
  • a tubal test such as an HSG
  • a hysteroscopy
  • thyroid tests
  • genetic carrier screening

Most of these tests are physically manageable. An HSG or hysteroscopy can cause cramping, so ask about pain relief beforehand. Emotionally, this stage can feel heavy, because results arrive as numbers that sound like verdicts. Ask what each result means for your plan, not just whether it is "normal".

Time commitment: usually one or two consultations plus test appointments. Some tests must happen on specific cycle days. Referrals, waiting lists or funding approval can add weeks or months.

Questions to ask:

  • What do my results mean for my treatment options?
  • Are you recommending IVF or ICSI, and why?
  • Should anything be treated first, such as a polyp, fibroid or hydrosalpinx?
  • Is counselling available or included?

Phase 2: Your protocol and medication preparation

Your clinic will recommend a stimulation protocol. Many people have an antagonist ("short") protocol. Others have an agonist ("long") protocol, which starts with a down-regulation phase to quieten your natural cycle. Some clinics offer milder or natural-cycle IVF in selected cases.

You might take the contraceptive pill or oestrogen beforehand to help schedule treatment. You will usually have an injection-teaching session and a written plan with doses and timings.

This is when the logistics become real: pens or vials, alcohol wipes, a sharps bin and a fridge shelf. A simple set-up helps:

  • Keep everything in one box.
  • Set phone alarms for a consistent time.
  • Stick the printed schedule on the fridge.
  • Note the out-of-hours number in case of a missed or spilled dose.
  • Ask a nurse to watch your first injection, and rotate sites as advised.

For many people, the anticipation turns out to be worse than the injection itself. On a long protocol, some people get headaches or temporary menopause-like symptoms during down-regulation.

Time commitment: from a few days to a few weeks depending on the protocol, plus one teaching appointment.

Questions to ask:

  • Which protocol are you using for me, and why?
  • What side effects should I expect?
  • Who do I call after hours if I make a medication mistake?
  • Is medication included in the quote or billed separately?

Phase 3: Ovarian stimulation and monitoring scans

During stimulation, daily hormone injections encourage several follicles to grow. Follicles are the fluid-filled sacs in the ovaries that may contain eggs. This phase commonly lasts around 8 to 14 days, depending on how you respond. Transvaginal ultrasounds and sometimes blood tests track progress, and your dose may be adjusted. Many protocols add a second injection part-way through to stop you ovulating too early.

You may feel bloated, tender, tired or more emotional than usual, and bruising at the injection site is common. As your ovaries enlarge, clinics usually advise low-impact movement. Intense twisting or high-impact exercise carries a small risk of ovarian torsion, where an enlarged ovary twists on its blood supply. Ask what is safe for you.

Emotionally, follicle counts can start to feel like exam results. Try not to compare your numbers with anyone else's. Response varies widely, and numbers never tell the whole story.

Safety note: ovarian hyperstimulation syndrome (OHSS) is an uncommon but potentially serious reaction to fertility drugs. Contact your clinic promptly if you have any of these:

  • severe bloating
  • worsening abdominal pain
  • rapid weight gain
  • shortness of breath
  • vomiting
  • dizziness
  • passing much less urine

If symptoms are severe, seek urgent medical care.

Talking to work: you don't have to share details. You could say: "I have a short series of medical appointments over the next two weeks and may need some flexibility with morning start times." In the UK, Acas publishes general guidance on time off and workplace rights. Elsewhere, check your national employment body.

Time commitment: this is the most diary-heavy phase. The injections take minutes but need consistent timing. Monitoring visits often fall every two to three days, usually early in the morning and sometimes at short notice. Keep mornings as flexible as you can.

Questions to ask:

  • How many monitoring visits should I expect, and at what times?
  • What would make you change my dose or cancel the cycle?
  • What are my personal risk factors for OHSS?
  • Which activities should I avoid during stimulation?

Phase 4: Trigger shot and egg retrieval (what it feels like)

When enough follicles look ready, your clinic schedules the trigger injection. It completes the final maturation of the eggs. Timing is precise, typically around 34 to 36 hours before retrieval, so set two alarms and follow the instructions to the minute.

Retrieval is usually done under sedation or anaesthesia, depending on the clinic and country. Guided by ultrasound, a doctor passes a fine needle through the vaginal wall and draws fluid from each follicle. The procedure is often short, commonly under half an hour, but plan for several hours at the clinic. On the same day, a sperm sample is provided, or frozen or donor sperm is thawed.

You may hear the number of eggs collected before you go home. Not every follicle contains an egg, and not every egg will be mature. After days of injections, that can sting. Let the clinic interpret the numbers before you decide what they mean.

Afterwards, cramping, spotting, bloating and sleepiness are common. Contact your clinic about severe or worsening pain.

Retrieval-day checklist:

  • Follow the fasting instructions exactly
  • Bring ID, paperwork and any outstanding consent forms
  • Wear loose clothes, slip-on shoes and warm socks
  • Pack sanitary pads (not tampons)
  • Skip nail polish and make-up if your clinic asks
  • Arrange a lift home. After sedation you should not drive or travel alone
  • Ask which pain relief is safe afterwards

Time commitment: a half or full day at the clinic. Most people take the day off, and many keep the next day quiet.

Phase 5: Fertilisation and embryo development in the lab

With conventional IVF, eggs and sperm are placed together in a dish. With ICSI, a single sperm is injected into each mature egg. ICSI is often used for male-factor infertility, after previous fertilisation problems, with frozen eggs, or for other clinical reasons.

Updates usually follow a pattern:

  • The day after retrieval: how many eggs fertilised.
  • Around day three: how the embryos are developing.
  • Day five or six: how many reached the blastocyst stage.

Expect the numbers to fall at each step. Fewer eggs fertilise than were collected, and fewer embryos reach blastocyst than fertilised. That narrowing is a normal part of IVF biology, not a sign that something has gone wrong. Knowing it in advance can soften those phone calls.

Embryo grading is a visual assessment that helps the lab choose which embryo to transfer or freeze. It is not a guarantee. Suitable embryos are frozen by a fast-freezing method called vitrification.

Some clinics offer preimplantation genetic testing (PGT). It can be recommended in specific situations, such as a known genetic condition. Routine use to improve outcomes is debated among specialists. Ask what it can and cannot tell you, and what it costs.

You may also be offered add-ons such as time-lapse imaging, assisted hatching or embryo glue. The evidence for them varies. The UK regulator, the HFEA, rates add-ons in plain language. It is a useful reference wherever you live.

Time commitment: little or no clinic time, with updates by phone or app over five or six days.

Questions to ask:

  • When and how will the lab update us?
  • What is your freezing policy, and what does annual storage cost?
  • What evidence supports any add-ons you suggest, and what do they cost?

Phase 6: Embryo transfer, fresh or frozen

A fresh transfer happens a few days after retrieval. A frozen transfer takes place in a later cycle, either a natural one or one prepared with medication. Your clinic may recommend freezing all embryos because of OHSS risk, your hormone levels, your uterine lining, genetic testing, or its usual protocol.

You will usually take progesterone, and sometimes oestrogen, to support the uterine lining. Progesterone comes as pessaries, gel or injections.

The transfer itself takes minutes and rarely needs sedation. A thin catheter is passed through the cervix into the uterus, usually guided by an abdominal ultrasound. Many people compare it to a cervical screening or Pap test. You will probably be asked to arrive with a comfortably full bladder. This can help straighten the angle of the uterus and gives a clearer ultrasound view. Many people find the full bladder is the most uncomfortable part, so follow the clinic's drinking timeline rather than overfilling hours ahead.

Elective single embryo transfer is widely recommended, especially with good-quality blastocysts. Carrying twins or more brings higher risks for both the pregnant person and the babies. Guidelines and legal limits vary by country, age, embryo stage and history, so ask how they apply to you.

Time commitment: allow around an hour at the clinic. Frozen transfers need a few scans or blood tests beforehand.

Questions to ask:

  • Fresh or frozen for me, and why?
  • How many embryos do you recommend, and what are the risks?
  • How long do I continue progesterone?
  • Are there any restrictions after transfer?

Phase 7: The two-week wait and pregnancy test

This is the gap between transfer and the clinic's blood or urine test. It is often around 9 to 14 days, depending on the embryo's stage and your clinic. Medically, there is little to do except take your medication exactly as prescribed. Emotionally, many people find it the hardest stretch of all.

Your symptoms cannot tell you the result. Progesterone can cause breast tenderness, bloating, tiredness, cramps and mild nausea whether or not an embryo has implanted. Try not to read these signs as proof either way. Light spotting can also have more than one cause. If you bleed or feel worried, call your clinic rather than guessing.

It is wise to skip early home testing. Many trigger shots contain hCG, the same hormone that pregnancy tests detect, so testing too early can pick up leftover medication. Testing too soon can also give a false negative.

A two-week-wait plan:

  • Pre-book small distractions for the evenings you expect to be hardest
  • Decide who hears the result first, and how
  • Choose where you want to be when the clinic calls
  • Mute forums if comparing makes you feel worse
  • Keep up gentle normal routines unless your clinic advises otherwise

Time commitment: few or no appointments. The load is emotional rather than logistical.

After the test: next steps either way

If the result is positive, you will usually have follow-up blood tests and an early scan, often around six to seven weeks. Your care then moves to an obstetrician, midwife or GP. It is normal for the anxiety to linger for a while.

If the result is negative, give yourself room to grieve. Then book a follow-up consultation to review the cycle and ask what might change next time. Frozen embryos can mean a quicker next step.

If your cycle was cancelled or no embryos developed, it is not a personal failure. It still gives your team useful information for planning.

IVF funding and access by country

Access depends on where you live, your age, diagnosis, relationship status and insurance. The rules change often, so always check current official sources before making decisions.

UK: national guidance recommends NHS-funded IVF for eligible patients. In practice, local areas decide what they fund, with criteria that can include age, BMI, smoking and existing children. The NHS IVF overview is a good starting point. Many people self-fund privately.

US: treatment is mostly private. Coverage depends on state insurance laws and your employer's plan, and medication is often billed separately. Ask for an itemised quote.

Canada: rules vary by province. Some provinces fund part of treatment, others offer tax support, and some offer little.

Australia: Medicare rebates cover part of the cost, but out-of-pocket gaps can be significant. Some states now offer public fertility services.

Germany: statutory insurers typically cover part of the costs for a limited number of attempts. Conditions include age limits and, under current rules, marriage. Some insurers and federal states add subsidies, and private insurance works differently.

France: national health insurance covers IVF to a significant degree within age and attempt limits. Access has been extended to single women and female couples.

Wherever you are, ask whether the price includes:

  • consultations
  • scans and blood tests
  • medication
  • anaesthesia
  • ICSI
  • freezing and storage
  • frozen transfers
  • add-ons

Questions to ask before choosing a clinic

  • What experience do you have with patients of my age and diagnosis?
  • Where are your success rates independently published?
  • Do you report live births or positive tests? Per embryo transferred or per cycle started?
  • What is included in the price, and what is extra?
  • What is your policy on single embryo transfer?
  • Who is my main contact, and how quickly do you respond?
  • What happens, and what do I pay, if my cycle is cancelled?
  • Is counselling included?
  • How do you handle urgent concerns out of hours?

Independent registers are more reliable than clinic marketing. Useful sources include:

Compare like with like: the same age group, the same measure, and live birth rather than a positive test.

Looking after yourself during IVF

IVF takes up space in your relationship, your work, your finances and your sense of self. You may feel hopeful at breakfast and furious by dinner. None of this means you are doing it wrong.

Share the load where you can. One person might handle medication alarms while another deals with insurance calls and meals. If you are going through IVF solo, choose a support person for retrieval day and result day.

Decide early what to tell people. A line like "We're having treatment and will share news when we're ready" keeps privacy without awkwardness.

There is no perfect IVF diet. Sensible basics are enough:

  • Don't smoke.
  • Follow your clinic's advice on alcohol and supplements, including folic acid.
  • Review your medications with your doctor.
  • Eat regularly and sleep where you can.
  • Move gently if you have been cleared to.

If anxiety, low mood or relationship strain feels unmanageable, ask about fertility counselling or speak to a qualified mental health professional. Patient organisations such as Fertility Network UK and RESOLVE in the US also offer support. This article is general information. Decisions about your treatment belong with your fertility specialist.

IVF FAQ

How long does the IVF process take from start to finish?

The active cycle commonly takes around four to six weeks. The full journey often runs for several months once tests, waiting lists, funding approval and any frozen transfers are included. It varies widely, and your clinic can give you a realistic timeline.

Does egg retrieval hurt?

Retrieval is usually done under sedation or anaesthesia, so most people don't feel the procedure itself. Cramping, bloating and spotting afterwards are common. Report severe or worsening pain to your clinic promptly.

Can I keep working during IVF?

Many people do. The pressure points are early-morning monitoring visits, retrieval day and, for some, the emotional strain of the two-week wait. Flexible hours often work better than full leave.

Should I take a home pregnancy test before the clinic's test?

It is generally best to wait. An hCG trigger can cause a false positive, and testing too early can give a false negative. Follow your clinic's timing, and call them if you bleed before the test.

How many IVF cycles might I need?

There is no single answer. It depends on age, diagnosis, ovarian response, embryo development and other factors. Ask your clinic for a personalised view, and look at independent register data rather than general averages.

Conclusion: a map, not a measure of your worth

On paper, the IVF process step by step looks tidy: tests, injections, retrieval, lab updates, transfer, test. In real life it is more stop-start, more emotional and more logistically demanding than most people expect.

Knowing what each phase involves helps you move from being swept along to making informed decisions with your care team. Ask questions. Get costs and success measures in writing. Take symptoms seriously. And remember that however your body responds, it is not a verdict on you, your choices or your future.
