At 30 weeks pregnant (30+0 to 30+6 weeks from the first day of your last period) you are about 6 months and 27 days along, moving from the 7th into the 8th month. As the NHS puts it, you are three-quarters of the way there. Your baby's eyes can now focus, and you may be dealing with poor sleep and getting out of breath on the stairs.
Counted from your last period, 30 weeks pregnant is about 6 months and 27 days: the end of the 7th month and the start of the 8th. This week covers days 210 to 216; you are in the third trimester, with about 70 days to your due date.
According to the NHS, your baby is about 39.9 cm long from head to heel. The eyes can now focus, and vision will keep developing inside and outside the womb. After birth your baby will be able to focus on your face from about 20 to 25 cm away, but will not follow moving objects with their eyes until about 3 months old.
ACOG's list for weeks 29 to 32 says the baby can stretch, kick and make grasping movements; the eyes sense changes in light; the bone marrow makes red blood cells; there may be some hair on the head; and lanugo starts to disappear.
The RCOG says the number of movements increases until 32 weeks.
You may find it hard to get to sleep, and have disturbing dreams when you do. The NHS says these dreams are fuelled by hormones and anxiety about the big changes ahead; they are not real, and talking about them helps put them in perspective. If you are feeling stressed, talk to your midwife or doctor.
Getting out of breath on the stairs is normal now, because your baby is pushing against your lungs (NHS).
It is a good time to get ready: pick up a few baby clothes, but not too many, as babies grow out of things very fast (NHS). Reading about the stages of labour is also recommended; if you have had a baby before, this birth may be different (NHS). The Turkish Ministry of Health guideline also includes counselling about labour, where you will give birth, breastfeeding and contraception after birth at the third visit.
Vaccine cut-offs. If you have not had the whooping cough (Tdap) vaccine, the Turkish guideline allows one dose until the end of week 32, and the NHS asks for it before week 33. The NHS offers the RSV vaccine around week 28 and says it can be given up until labour; in the US practice described by UpToDate it is given between 32+0 and 36+6 weeks during RSV season.
How much does the baby weigh? In the reference table of the World Health Organization's fetal growth study across 10 countries (2017), the median (50th percentile) estimated weight at 30 weeks is about 1,523 g; the 10th percentile is 1,313 g and the 90th percentile 1,753 g. These are reference values, not your own baby's measurement. The study notes differences between countries, maternal characteristics and the baby's sex, so these charts may need adjusting for local use. The growth trend matters more than a single measurement.
| Symptom | Usually | Seek care if |
|---|---|---|
| Poor sleep and disturbing dreams | Common because of hormones and worries about the birth; talking about your dreams helps. | Tell your midwife or doctor if you feel stressed or too tired to cope (NHS). |
| Out of breath on the stairs | Normal now because your baby is pushing against your lungs. | Get help straight away for breathlessness at rest, fast breathing or chest pain (Turkish Ministry of Health guideline, 2026). |
| Swollen feet | Can be caused by gravity in late pregnancy (Turkish Ministry of Health guideline, 2026). | Swelling of the hands or eyelids can be an early sign of pre-eclampsia; tell your midwife or doctor so your blood pressure can be checked (Turkish Ministry of Health guideline, 2026; NHS). Get help straight away for swelling of the face, sudden, rapidly increasing swelling of the hands or legs, or swelling with a headache, vision problems or pain below the ribs. |
Contact your midwife, doctor or maternity unit straight away if you have:
Most of these are danger signs or emergency referral criteria in the Turkish Ministry of Health Antenatal Care Management Guideline (2026); tightenings, cramps, backache and pelvic pressure are on UpToDate's list of preterm labour signs. Headache, vision problems, facial swelling, pain below the ribs and high blood pressure can be signs of pre-eclampsia (NHS, UpToDate). The NHS says to call if your baby's movements reduce, stop or change, without waiting until the next day, even at night. The RCOG says that after 28 weeks you must get help immediately; your baby's heart rate is usually monitored for at least 20 minutes. Do not rely on a home doppler.
It is in between. From your last period, 30 weeks is about 6 months and 27 days, so you are at the end of the 7th month and move into the 8th during this week. The answer to "how many months" depends on how many days you count in a month, so pregnancy is tracked in weeks and days, such as 30+0. ACOG also notes that gestational age is usually reported in weeks and days.
Under the Turkish guideline, 140/90 mmHg or higher is high blood pressure in pregnancy; weekly checks are advised from 32 weeks, and you should see a doctor if it is above 130/80 mmHg. If you get a reading of 160/110 mmHg or higher, seek emergency care straight away. Under the Turkish guideline, staff repeat the reading after 15 minutes and, if it is still high, arrange emergency transfer by ambulance (112). NICE recommends that a woman with a first reading of 140/90 mmHg or higher after 20 weeks is seen within 24 hours, and the same day at 160/110 mmHg or higher.
Yes, they are common. The NHS says disturbing dreams come from hormones and anxiety about the changes ahead, and are not real. Try sleeping on your side with pillows under your bump and between your legs; if you feel stressed, tell your midwife or doctor.
The NHS says the baby's eyes can now focus, and ACOG says that during weeks 29 to 32 the eyes can sense changes in light. Vision keeps developing after birth.
In the reference table of the World Health Organization fetal growth study (2017), the median estimated weight at 30 weeks is about 1,523 g, with the 10th percentile at 1,313 g and the 90th at 1,753 g. These are reference values; an ultrasound weight is itself an estimate with a margin of error, so the growth trend matters more than a single measurement.
