Week 4 of Pregnancy
If you have a regular menstrual cycle, you may have noticed one of the first signs of pregnancy: a missed period. Now would be a good time to take a urine test or blood screening to confirm that you are expecting.
And while you have been pregnant for about two weeks, this is your first month of pregnancy in medical terms. Congratulations, now you have nine more months to go! Remember, a normal term lasts 40 weeks.
At this stage your baby is very tiny – about the size of a poppy seed.
The little one is in the embryonic phase. The embryo is growing and developing within a small yolk sac in the endometrial (uterine) lining. This yolk sac will later be incorporated in your baby’s digestive tract to provide nourishment and sustenance, and it also produces blood.
