Pregnancy in Québec, week by week
Week 3 of pregnancy: the baby, you, and Québec
Week 3: fertilization has just happened and the egg is travelling to the uterus; you probably do not know yet.
Your baby
Implantation
About a week after fertilization, the egg implants in the lining of the uterus: implantation. Weeks of pregnancy are counted from the first day of the last period, so at “3 weeks” conception is barely a week old. A pregnancy test becomes reliable once the period is late.
You
Folic acid and a multivitamin
A prenatal multivitamin with folic acid is recommended from the moment you plan a pregnancy and through the first trimester at least. The right product is chosen with the pharmacist or your professional; this page gives no dose.
Mood matters too
Anxiety and depression can begin during pregnancy, not only after. According to the INSPQ they are treatable, and the sooner the better. If worry or sadness has taken over for more than two weeks, talk to your professional, the CLSC or 811, where Info-Social also answers.
