Pregnancy week 3

Trimester 1 · Baby is about a cluster of cells, about the size of a pinhead

The fertilised egg divides as it travels down the fallopian tube towards the uterus.

  • A little spotting can happen as implantation begins.
  • Mild bloating is common.

Self-care this week

  • Continue folic acid.
  • Avoid alcohol, smoking and unprescribed medicines.
  • Keep meals balanced — no need to eat for two.
