14 weeks pregnant means 14+0 to 14+6 weeks from the first day of your last period: about 3 months and 7 days, so you are in the 4th month. By ACOG's definition the second trimester starts this week; for many people tiredness and nausea ease and appetite returns.
14 weeks pregnant (14+0 to 14+6 weeks) is about 3 months and 7 days from the first day of your last period. You are in the 4th month and in the first week of the second trimester.
The NHS says your baby is now about 8.5 cm from head to bottom, about the size of a kiwi fruit. The head is getting rounder and more in proportion with the body. Your baby is kicking, but you probably won't feel it yet. Small amounts of amniotic fluid are swallowed, pass into the stomach, the kidneys get to work and the fluid is passed back out as urine.
ACOG's summary for weeks 13 to 16 says the long bones harden, the neck becomes defined, the legs develop and hearing starts to develop, while the skin is still thin and see-through.
As tiredness and nausea fade, your appetite may grow. The NHS says your baby does not need extra calories at this point and that gaining too much weight is not good for you or your baby, so choose healthy snacks. The placenta carries nutrients, oxygen and hormones to your baby and removes waste; your blood and your baby's blood come into close contact there but do not mix.
You may notice yellow stains in your bra: this is probably colostrum, the first milk. Advice on sleep position differs: the NHS says sleeping on your front is fine early on, but after 28 weeks it is safest to go to sleep on your side to reduce the risk of stillbirth; UpToDate notes that case-control studies have linked sleeping on the back in late pregnancy with stillbirth, while a large prospective study that measured sleep position at 22 to 30 weeks found no significant increase in poor outcomes among people who slept on their back more than 50% of the time; that study does not cover the weeks after 30.
Under the Turkish Ministry of Health guideline (2026) the first visit takes place within the first 14 weeks; anyone whose pregnancy is first seen after 14 weeks has a full first visit whatever the week. The next routine visit is between 18 and 24 weeks. If combined screening was not done, the guideline offers the triple/quad test at 16 to 20 weeks, while ACOG offers the quad test at 15 to 22 weeks.
NICE NG201 recommends a 16-week (14 to 18 weeks) appointment with a blood pressure check, a urine test for protein and a discussion of earlier test results. In the USA, low-risk pregnancies are usually seen every four weeks until 28 weeks (UpToDate, 2026).
There is no routine screening scan in these weeks: in the NICE schedule the next scan after the 11–14-week scan is at 18 to 20 weeks. Sources differ on hearing the heartbeat: the NHS says your midwife may be able to hear it with a handheld monitor this week, while the Turkish Ministry of Health guideline says it can be heard with a handheld Doppler from 16 weeks. The NHS advises against using a home Doppler: hearing a heartbeat does not mean your baby is well.
| Symptom | Usually | Seek care if |
|---|---|---|
| Brief sharp pains on the sides of the bump | Round ligament pain from the growing womb is common (NHS). | If the pain is severe, does not settle, or comes with bleeding, fever or leaking fluid. |
| Yellowish leak from the breasts | This is probably colostrum (NHS). | Ask your midwife or doctor to check any breast change that worries you (NHS). |
| Mild swelling of hands and feet | The NHS lists it among symptoms at this stage. | Get help if your face, hands or legs become noticeably or suddenly swollen (a Turkish Ministry of Health danger sign). |
These are danger signs or emergency referral criteria in the Turkish Ministry of Health guideline; contact your doctor or go to the nearest emergency department without waiting. NICE recommends a hospital review for any unexplained bleeding after 13 weeks, and anti-D for women who are RhD negative and at risk of isoimmunisation.
Days 98 to 104 from the first day of your last period, or about 3 months and 7 days. You are in the 4th month; according to ACOG the second trimester runs from 14 weeks 0 days to 27 weeks 6 days.
Usually not reliably on ultrasound yet; UpToDate notes that ultrasound generally shows the sex at 17 to 20 weeks. The NHS says the sonographer may be able to tell you at the scan around 18 to 20 weeks, but not every hospital's policy is to reveal it. A cell-free DNA test (NIPT) can report the sex along with chromosome screening; a wrong result is possible.
The NHS says most women gain 10 to 12.5 kg in total, usually after week 20. The Turkish Ministry of Health guideline sets targets by pre-pregnancy body mass index (BMI) and recommends no more than 2 kg a month for underweight or normal-weight women and no more than 1 kg a month for overweight or obese women:
| Pre-pregnancy BMI (kg/m²) | Total gain (kg) | Weekly gain in 2nd and 3rd trimester (kg) |
|---|---|---|
| Underweight (<18.5) | 12.5–18.0 | 0.51 (0.44–0.58) |
| Normal (18.5–24.9) | 11.5–16.0 | 0.42 (0.35–0.50) |
| Overweight (25.0–29.9) | 7.0–11.5 | 0.28 (0.23–0.33) |
| Obese (≥30.0) | 5.0–9.0 | 0.22 (0.17–0.27) |
Sources differ: the NHS says your midwife may hear it with a handheld monitor this week, while the Turkish Ministry of Health guideline says a handheld Doppler can pick it up from 16 weeks. The heartbeat has been visible on ultrasound since earlier weeks. Do not listen with a home Doppler: the NHS says it is not a reliable way to check your baby's health.
According to the WHO fetal growth charts (2017), the median (50th percentile) estimated fetal weight at 14 weeks is 90 g, and the 10th to 90th percentile range is 78 to 104 g. These are reference values from ultrasound measurements in low-risk pregnancies in ten countries; the authors note differences between countries, with maternal factors and with fetal sex, and say the charts may need adjusting for local use. UpToDate adds that ultrasound weight estimates are generally not useful before about 24 weeks. The NHS gives a length of about 8.5 cm from head to bottom.
