In your fourth week of pregnancy, exciting changes are happening within your body! Your little one is still incredibly tiny—about the size of a poppy seed—but this is a crucial time as your body begins to develop the placenta and amniotic sac.
What’s Happening with Your Body:
As the cluster of cells that will become your baby embeds itself into the uterine lining, you might experience some symptoms like mild abdominal pressure and tender breasts. Some women even notice a little spotting, known as implantation bleeding, though it’s perfectly normal if you don’t have any symptoms yet.
Your Baby at Week 4:
- Two Sets of Cells: Your tiny embryo consists of two layers of cells called the epiblast and the hypoblast. These will eventually develop into all of your baby’s organs and systems.
- Seeing Double: While your first ultrasound is typically scheduled around week 6, you might catch a glimpse of the gestational sac in the latter half of week 4. If you’re expecting twins, you may even see two sacs!
- Yolk Sac Development: Before the placenta fully forms, a yolk sac will develop, which provides vital nourishment for your growing embryo.
