As A Life Health Group, we are here to provide you with the most accurate and up-to-date information and support you at every moment of your 16-week pregnancy journey. We have prepared a comprehensive information page about this exciting period. On this page, you will learn in detail what happens in the sixteenth week of pregnancy, the changes occurring in your body and your baby, what to pay attention to, and what the second trimester brings you.

What Does 16-Week Pregnancy Mean?

Pregnancy is calculated from the first day of your last menstrual period. At 16 weeks of pregnancy, your baby measures approximately 11–12 cm and is about the size of an avocado. This week marks a period in which your baby continues to grow steadily in the second trimester, movements become more noticeable, and the senses further develop.

Your baby’s bones continue to harden and muscles strengthen. This week, your baby’s eyes begin to move, and they can turn their head. Additionally, your baby’s heart beats more strongly, and circulation improves. In first pregnancies, mothers may start to feel their baby’s movements during this week.
