symptoms at 30 weeks
- Insomnia
- A crowded bladder, active baby, racing mind, and awkward positions gang up on sleep now. A wind-down routine and side-sleeping pillow set-up help; short daytime naps fill the gaps.
- Stronger Braxton Hicks
- Practice tightenings get noticeably firmer at this stage but remain irregular and settle with rest. Regular, painful, or intensifying tightenings before 37 weeks mean calling your midwife or doctor.
- Breathlessness and rib pressure
- The uterus is near its highest point relative to your lungs. Relief usually comes in the mid-to-late thirties weeks when the baby drops into the pelvis.
- Mood swings and pre-birth anxiety
- Worries about labour, the baby, and the life change ahead can loom large at night. Talking to your midwife is worthwhile if anxiety is affecting your daily life — support exists and asking is normal.
- Frequent urination returns
- Pressure on the bladder increases again as the baby grows and descends. Keep drinking water regardless — cutting fluids risks dehydration and does not help much.
- Itchy bump
- Skin is near maximum stretch. Moisturise freely, and remember that intense itching involving palms and soles needs a call to your midwife or doctor to rule out cholestasis.
gentle tips
- Pack the hospital bag and finalize the birth plan.
- Discuss pain management and birth preferences with your provider.
- Practice breath-work daily — useful in labor.
- Eat folate, iron, calcium, and protein-rich foods consistently.
- Talk to baby — the voice is recognized at birth.
your week 30 checklist
- Write down your birth preferences properly and bring them to your next appointment for discussion.
- Order or gather your hospital bag items so packing at week 35 is assembly, not shopping.
- Wash the first batch of newborn clothes and bedding in gentle detergent.
- Confirm who your emergency contacts and backup birth partner are if your first choice is unavailable.
what to expect next
Many babies turn head-down (cephalic) over the next month. Stay attentive to position checks at prenatal visits.

What should I do at 30 weeks pregnant?
Many babies turn head-down (cephalic) over the next month. Pack the hospital bag and finalize the birth plan. Discuss pain management and birth preferences with your provider. Practice breath-work daily — useful in labor.
Should I worry that my baby is breech at 30 weeks?
Not yet — around a quarter of babies are breech at 30 weeks, and most turn head-down on their own by 36 weeks as they run out of room. Your midwife will keep checking position at each appointment. If your baby is still breech around week 36, your team will discuss options with you, including a manual turning procedure called ECV.
How do I tell Braxton Hicks from real contractions?
Braxton Hicks are irregular, usually painless, do not build in strength or frequency, and typically stop when you rest, move, or drink water. Real labour contractions become regular, last longer, get closer together, and grow stronger regardless of what you do. If you are before 37 weeks and getting regular or painful tightenings, call your midwife or maternity unit rather than waiting to be sure.
What helps with pregnancy insomnia in the third trimester?
The evidence-backed basics are a consistent wind-down routine, a cool dark room, limiting screens before bed, and a pillow arrangement that supports the bump and keeps hips stacked. Accept that broken sleep is partly physiological now and take short daytime naps without guilt. Avoid sleep medications and supplements unless your doctor has specifically approved them for pregnancy.
