Week 5 of Pregnancy: Significant Developmental Milestones

Baby Size at Week 5 At week 5 of pregnancy, your baby is about the size of an apple seed. This is a period of rapid development. The embryo’s major organs, including the heart, start to form. Interestingly, the heart begins to beat, although it may still be too early to detect via ultrasound. With about 35 weeks until the expected date of delivery, this stage marks a significant milestone in fetal development.

Changes and State in the Mother’s Body

During the fifth week, your body is undergoing significant changes to support the growing embryo. The levels of pregnancy hormones, especially hCG, continue to rise, leading to some of the early signs of pregnancy. For many women, this week marks the beginning of morning sickness, a common symptom characterized by nausea and sometimes vomiting.

The uterus continues to prepare for the growing baby, and while you might not notice much physical change externally, there’s a lot happening inside.

Common Symptoms

The symptoms during week 5 can be quite pronounced for some women, including:

  • Morning sickness (nausea and vomiting)
