The third trimester: what to expect

The third trimester begins at week 28. The third trimester means a lot of wonderful things including baby showers, guaranteed seats on trains and buses, choosing baby names, relishing that thick pregnancy hair, getting your baby room ready and free dental work (who knew!?).

But over the next couple of months as your baby grows and grows, you’ll probably start to feel more tired than during the second trimester. As always, there are lots of new symptoms (spoiler: none of them are particularly fun) to expect in the third trimester. These include:

  • Difficulty sleeping 

  • Pelvic pain

  • Stretch marks

  • Nose bleeds

  • Gum problems

  • Constipation

  • Haemorrhoids or piles

  • Headaches

  • Reflux

  • Swollen hands and feet

  • Urinary tract infections

  • Vaginal infections


Don’t forget to always seek medical help if you’re experiencing any serious symptoms. In particular, needing to pee very frequently or pain while peeing can be a sign of a urinary tract infection, which should always be treated by your doctor, and swelling can be a sign of pre-eclampsia, so it’s best to get checked out.
