At 4 weeks pregnant, your baby is about the size of a poppy seed, and exciting changes are happening in your body. This week marks the beginning of the formation of the placenta and amniotic sac. Symptoms such as abdominal pressure and tender breasts may arise, and as the tiny cluster of cells that will become your baby implants into the uterine lining, you might notice some implantation bleeding. However, it’s completely normal if you experience no symptoms at all.
Your Baby at Week 4
- Two Sets of Cells: Your tiny embryo comprises two layers of cells known as the epiblast and hypoblast. These will soon develop into all of your baby’s body parts and systems.
- Seeing Double: Although you typically won’t have your first ultrasound until around week 6, you may be able to detect the gestational sac as early as mid-week 4. If you’re expecting twins, you might see both sacs!
- Baby’s Yolk Sac: Before the placenta fully forms, a yolk sac develops, which will be visible next week. This sac is crucial as it produces blood and nourishes your growing embryo.
