Your bump is growing fast, and you may notice heartburn after meals. The NHS says to tell your midwife if you haven't felt your baby move by 24 weeks.
Things to do this week
- Ask about the gestational diabetes screening if you're offered it.
- Eat smaller meals and avoid lying down right after eating to ease heartburn.
- Tell your midwife now if you haven't felt any movements.
When to call your doctor or midwife
Contact your care team straight away if:
- your baby's movements slow down or change once you've started feeling a pattern, or you haven't felt any movement by 24 weeks
- you have a severe headache, vision changes, pain just below your ribs, or sudden swelling of your face, hands or feet (possible signs of pre-eclampsia)
- you have regular contractions, pelvic pressure or a low, dull backache before 37 weeks
- you have bleeding or fluid leaking from your vagina
- you have a fever of 100.4°F (38°C) or higher
If something feels wrong, trust that feeling and call. In an emergency, call your local emergency number.
