What to expect
Early pregnancy can feel invisible from the outside and very loud on the inside. Symptoms come and go from day to day, and that is normal. With 33 weeks to go, the priority this week is rest, gentle food and your first antenatal appointment.
Tips for this week
- Rest without guilt. First-trimester tiredness is real and temporary.
- Eat small, frequent meals; an empty stomach makes nausea worse.
- Keep moving gently — a daily walk helps circulation, mood and sleep.
