At 30 weeks pregnant, you are firmly in the third trimester. The baby is growing fast, movement is usually strong, and many providers begin paying closer attention to baby position and birth preparation.
This week follows 29 weeks pregnant and leads into 31 weeks pregnant. If you want to compare dates or estimate the due date, use the pregnancy calculator.
The baby may be around 38-40 cm long and weigh roughly 1.3-1.5 kg, though size estimates vary. The head may already be down, but if not, there is still time for the baby to turn.
Lungs, brain and muscles are maturing, the skin is becoming less wrinkled, and body fat is still increasing. Babies at this stage often have stronger movement patterns and may react to familiar voices, sound and touch.
Many parents notice that kicks are stronger under the ribs or across the side of the bump. A more stable sleep-wake rhythm may also make movement feel more predictable than earlier in pregnancy.
Back pain, swelling, shortness of breath, heartburn, leg cramps, tiredness and Braxton Hicks contractions are all common at this stage. Your bump is larger, so it may take more effort to sleep, walk or sit comfortably for long periods.
Some providers start checking fetal position more carefully from around this time, especially if the baby has not settled head down yet. If you have bleeding, fluid leakage, severe headache, vision changes, painful regular contractions or reduced movement later in pregnancy, seek advice promptly.
Birth planning often becomes more practical now: labour signs, where to go, who to call, and what you still need to pack or buy. That is normal and useful work for this point in pregnancy.
Vertex position means the baby is head down and ready for birth in the most common position.
Braxton Hicks are irregular tightening sensations in the uterus that can become more common in the third trimester.
Reduced movement later in pregnancy means movement feels clearly less than your baby's usual pattern and should be checked.
Thirty weeks pregnant is often described as about 7 and a half months pregnant, but weeks are more exact than months.
30 weeks pregnant is in the third trimester.
Many babies are head down by 30 weeks, but some are still turning. Your provider will keep checking position as pregnancy progresses.
Back pain, swelling, heartburn, shortness of breath, leg cramps, Braxton Hicks and tiredness are all common as the third trimester progresses.
Call promptly for regular painful contractions, bleeding, fluid leakage, severe headache, vision changes, or a clear reduction in movement later in pregnancy.
