IVF Pregnancy Calculator — Week 32 (Day 3 & Day 5 Transfer)
You are 32 weeks pregnant after IVF (gestational age counted from egg retrieval + 14 days for day-5 transfer, +12 days for day-3 transfer). Below is what your embryologist and REI clinic expect at this exact stage.

Enter your egg retrieval date and select day-3 or day-5 transfer. EDD = retrieval + 266 days.
Baby at week 32
At 32 weeks gestational after IVF transfer: Fingernails reach fingertips. Practising suck-swallow-breathe coordination. Position usually head-down soon.
Mother's body — what changes
Post-IVF at week 32, clinical picture: Colostrum flows more. Fatigue. Braxton-Hicks may confuse with early labour.
Nutrition & supplements
Add ~450 kcal/day. Increase iron and DHA — brain growth peaks now. Split meals into 5–6 small portions to control heartburn and stable glucose. Post-IVF continue progesterone support and prenatal vitamin exactly as your REI prescribed. Do not add herbal supplements without clearance — many interact with luteal support.
Safe exercise
Reduce intensity but keep moving. Pelvic floor + squats prepare for labour. Avoid contact sports, ski, horse-riding and hot yoga. After IVF avoid high-impact activity until confirmed viability at 8-week scan. Then follow standard trimester guidance.

Week 32 — Frequently asked questions
How accurate is the IVF Pregnancy Calculator at week 32?
The calculator uses standard gestational-age arithmetic (LMP + 280 days for standard; egg retrieval + 266 days for IVF day-5). Ultrasound crown-rump length between weeks 8–13 is more accurate (±5 days) than LMP — adjust EDD accordingly if the scan differs by more than 7 days.
What size is my baby at week 32?
Approximately the size of a large jicama — length 42.4 cm and weight 1700 g. These are median values from ASRM, SART and ESHRE references.
Which symptoms are normal in week 32?
Colostrum flows more. Fatigue. Braxton-Hicks may confuse with early labour. Every pregnancy is different — call your provider if anything on the warning-signs list appears.
Should I have an ultrasound at week 32?
Confirm baby position (head-down vs breech) at next visit. Routine scan windows are: dating (10–13w), anatomy (18–22w), growth (28–32w).
How much weight should I gain by week 32?
Approximately 10.5 kg cumulative if you started at a normal BMI (IOM guideline). Underweight mothers gain more; overweight mothers less.
Day 3 vs Day 5 transfer at week 32 — what's the difference?
Day-5 blastocyst transfer adds 5 days to embryo age; Day-3 transfer adds 3 days. Gestational age = transfer date + (14 − transfer day) days + weeks since transfer. Both converge on the same due date; the difference matters only in the first 2 weeks.
Should I continue progesterone at week 32?
Most REI clinics wean progesterone by week 12. Follow your clinic's exact taper — abrupt stop before placental takeover risks miscarriage.
