Baby’s Growth & Development
During the 4th week of pregnancy, your baby is the size of a sesame seed. During this time, your baby’s brain will begin to develop along with their spinal cord. Other major organs such as the heart, placenta, and sac will also start to develop.
Your Body During Week 4
Week 4 of pregnancy can be filled with several symptoms such as sore breast, nausea, fatigue, and the most common one, a missed period. You might experience implantation bleeding, which some women mistake for their period. It is also normal to feel some cramping during this time. This is caused by the embryo embedding itself in your uterine wall. If you experience excessive cramping and heavy bleeding, contact your doctor right away.
