A single IVF cycle takes approximately 4–6 weeks from the start of ovarian stimulation to the pregnancy test. Including the initial consultation, diagnostic testing, and treatment planning, expect the entire process from first appointment to knowing if you’re pregnant to take 2–4 months. A frozen embryo transfer (FET) adds an additional 4–6 weeks after the retrieval cycle.
- The pre-cycle phase (consult, testing, insurance) typically takes 4–8 weeks and is the part most people underestimate
- Ovarian stimulation lasts 8–14 days, with daily injections and monitoring every 2–3 days
- Egg retrieval is a 15–30 minute outpatient procedure under sedation; most patients return to normal activities within 1–2 days
- If doing a freeze-all protocol (now standard at most clinics), embryo transfer happens in a separate FET cycle 1–3 months later
- The two-week wait between embryo transfer and pregnancy test is the hardest part — not physically, but emotionally
Phase 1: Pre-Cycle (Weeks 1–6)
Week 1–2: Initial Consultation
Your first appointment with a reproductive endocrinologist (RE) typically lasts 45–90 minutes. The RE will review your medical history, prior testing, and discuss initial treatment recommendations. Expect questions about your menstrual cycle, prior pregnancies or losses, sexual history, and family medical history.
Week 2–4: Diagnostic Testing
Before starting IVF, your clinic will order baseline testing for both partners:
| Test | What It Measures | When in Your Cycle |
|---|---|---|
| AMH (Anti-Müllerian Hormone) | Ovarian reserve (how many eggs remain) | Any time |
| Day 3 FSH + Estradiol | Ovarian function baseline | Cycle day 2–4 |
| Antral Follicle Count (AFC) | Visible resting follicles via ultrasound | Cycle day 2–5 |
| TSH, Prolactin | Thyroid and hormonal balance | Any time |
| HSG or SHG | Uterine cavity and tubal patency | Cycle day 6–12 |
| Semen Analysis | Sperm count, motility, morphology | 2–5 days abstinence |
| Infectious disease panel | HIV, Hepatitis B/C, RPR (both partners) | Any time |
Week 4–6: Treatment Planning + Insurance
Your RE designs a personalized stimulation protocol based on your test results. Common protocols include long lupron, antagonist, and micro-dose flare. Your clinic’s financial coordinator will run your insurance benefits (verification of benefits, or “VOB”) and provide a cost estimate. This is also when you’ll complete consent forms and order medications.
IVF medications are typically shipped from a specialty pharmacy 1–2 weeks before your cycle begins. They require refrigeration. Your clinic or pharmacy will schedule an injection training session — either in person or by video — to teach you how to prepare and administer the injections.
Phase 2: Stimulation (Days 1–14)
Days 1–3: Starting Medications
You’ll begin injectable gonadotropins (brand names include Gonal-F, Follistim, and Menopur) on cycle day 2 or 3. These stimulate your ovaries to produce multiple follicles instead of the single egg a natural cycle would produce. Injections are subcutaneous (into belly fat with a small needle) and typically take 5–10 minutes including preparation.
Days 4–8: Monitoring Begins
Starting around day 4–5, you’ll visit the clinic every 2–3 days for transvaginal ultrasound and blood work. These appointments are usually early morning (6:30–8:30 AM) and take 20–45 minutes including wait time. Your RE adjusts medication doses based on how your follicles are growing.
Days 8–12: Adding the Antagonist
Once follicles reach approximately 13–14mm, most protocols add a GnRH antagonist (Cetrotide or Ganirelix) to prevent premature ovulation. Monitoring increases to every 1–2 days. Expect 4–7 monitoring visits total during stimulation.
Day 10–14: Trigger Shot
When your lead follicles reach 18–22mm, your clinic will instruct you to take the “trigger shot” (hCG or Lupron trigger) at a very specific time. This triggers final egg maturation. Egg retrieval will be scheduled exactly 34–36 hours after the trigger.
Phase 3: Retrieval + Fertilization (Days 14–20)
Retrieval Day
Egg retrieval is an outpatient procedure performed under IV sedation (you’ll be asleep but not under general anesthesia). Using ultrasound guidance, the RE inserts a thin needle through the vaginal wall to aspirate fluid from each follicle. The procedure takes 15–30 minutes. You’ll recover for 30–60 minutes and can go home the same day. Plan to take the day off work. Most patients feel bloated and crampy for 1–3 days.
Days 1–6 After Retrieval: The Embryology Lab
This is where the embryologist takes over:
- Day 0: Eggs are identified and mature eggs are inseminated (conventional IVF or ICSI)
- Day 1: Fertilization check — you’ll learn how many eggs fertilized normally (2PN embryos)
- Day 3: Embryos reach 6–8 cell stage. Some clinics do day-3 transfers, though day-5 is now standard
- Day 5–6: Surviving embryos reach blastocyst stage. These are graded, and if doing PGT-A, biopsied and frozen
Attrition is normal at every stage. If 15 eggs are retrieved, perhaps 12 are mature, 9 fertilize, 5 make it to day 5, and 3 are genetically normal (if tested). This “funnel” is a source of significant anxiety. Your RE should prepare you for expected attrition rates based on your age and diagnosis.
Phase 4: Embryo Transfer (FET Cycle)
Most clinics now use a freeze-all protocol, meaning all viable embryos are frozen and transfer happens in a subsequent cycle. This allows your body to recover from stimulation and optimizes the uterine lining for implantation.
FET Prep: 2–4 Weeks
A typical medicated FET cycle begins with estrogen (patches, pills, or injections) to build the uterine lining. After 10–14 days, an ultrasound confirms adequate lining thickness (ideally 7mm+). Progesterone support (injections, suppositories, or both) begins 5 days before transfer.
Transfer Day
Embryo transfer is a 5–15 minute procedure, typically without anesthesia. Using ultrasound guidance, the RE threads a thin catheter through the cervix and places the embryo in the uterus. It feels similar to a Pap smear. Most patients return to normal activities the same or next day.
Phase 5: The Two-Week Wait
After transfer, you’ll wait approximately 9–12 days for a beta hCG blood test. This is the pregnancy test. Many patients describe this as the hardest part of IVF — the uncertainty is intense. Your clinic will advise you to avoid home pregnancy tests before the blood draw, as they can produce false negatives (too early) or false positives (residual trigger shot hCG).
If the beta is positive, a second blood draw 48 hours later confirms the hCG is rising appropriately. A viability ultrasound at 6–7 weeks confirms a heartbeat. At that point, most clinics will “graduate” you to your OB/GYN.
