Pregnancy, week by week
From week 4
to week 42.
Every week of pregnancy, from week 4 to week 42: how your baby is growing, what you may feel, and what not to miss, for parents in Canada, in four languages.
Weeks are counted from the first day of your last period, as your care team counts them.
Trimester 1
Trimester 2
Trimester 3
