Pregnancy Countdown Calculator

Enter the first day of your last menstrual period (LMP). EDD = LMP + 280 days.

Baby at week 9

With 9 weeks left, your baby has already: Embryo becomes a fetus. Tiny tail disappears. Tooth buds form under the gums. External genitalia begin to differentiate.

Mother's body — what changes

With 9 weeks to go, your body is: Waistband tightens. Nose may be congested (rhinitis of pregnancy). Vivid dreams are common.

Nutrition & supplements

Focus on folic acid 400–600 mcg/day (neural tube), iodine 150 mcg, and small frequent meals to counter nausea. No extra calories yet — normal maintenance intake is adequate. With only 9 weeks left, focus on iron-rich foods to build baby's stores for the first 6 months of life, and vitamin K-rich leafy greens.

Safe exercise

150 minutes/week of moderate activity — brisk walking, stationary cycling, prenatal yoga. Stop any exercise that leaves you unable to hold a conversation. With 9 weeks left, prioritise perineal massage, pelvic tilts and squats — active preparation for the pushing stage.

Week 9 — Frequently asked questions

How accurate is the Pregnancy Countdown Calculator at week 9?

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 9?

Approximately the size of a grape — length 2.3 cm and weight 2 g. These are median values from NHS antenatal guidance and ACOG term-delivery references.

Which symptoms are normal in week 9?

Waistband tightens. Nose may be congested (rhinitis of pregnancy). Vivid dreams are common. Every pregnancy is different — call your provider if anything on the warning-signs list appears.

Should I have an ultrasound at week 9?

Discuss NIPT (non-invasive prenatal testing) — available from week 10. Routine scan windows are: dating (10–13w), anatomy (18–22w), growth (28–32w).

How much weight should I gain by week 9?

Approximately 1.3 kg cumulative if you started at a normal BMI (IOM guideline). Underweight mothers gain more; overweight mothers less.

What should I pack 9 weeks before due date?

Hospital bag essentials: ID + insurance, birth plan, comfortable labour clothes, going-home outfit for baby (0–3M), 3 nursing bras, maternity pads, phone charger, snacks. Pack the bag by week 36 regardless of your 9-week countdown.

Signs of labour at 9 weeks to go?

Regular contractions <5 minutes apart lasting >60 seconds, waters breaking (gush or slow leak), bloody show (mucus plug + streak), and 4+ cm cervical dilation. Go to hospital when contractions are 5-1-1 (every 5 min, lasting 1 min, for 1 hour).
