You have reached the 10th week of pregnancy, each week of which is a different excitement. You are wondering what awaits you and your baby this week. Week 10 is a big week for your baby! This week marks the transition to the fetal stage, which lasts until birth. After that, it will grow and develop until it is ready for life outside the womb. So, how big is a 10-week baby? Can you tell the sex of the baby at 10 weeks?

Yeditepe University Hospitals Gynecology and Obstetrics Department Head and IVF Specialist Prof. Dr. Erkut Attar answered our questions. Here is the 10-week pregnancy process and the baby's development...

How Big is a 10-Week baby?

With a head-to-butt length of about 3.1 cm and weighing about 4 g, your baby is the size of a strawberry and will triple in size over the next 3 weeks.

Baby Development at 10 Weeks of Pregnancy

Its head is now more rounded and upright, the outer part of its ears is fully developed, and its legs are well formed. The eyelids are closed and will stay that way until about 27 weeks of pregnancy. The ears continue to develop on the sides of your baby's head. On your baby's face, you can see the upper lip and two small nostrils in the nose. The jaw bones are developing and already contain all future milk teeth. Its tiny fingers and toes are no longer webbed, its arms and legs can rotate at the shoulder and hip joints and its hands can meet over its heart. It is small but quite active, kicking with its legs and reaching out to touch its face with its hands.

This week, the nails on your little fingers start to develop and the hair starts to grow. The yellow sac (yolk sac) that provides nutrients to your baby before the placenta develops will soon shrink.

Your baby has a fully developed heart that beats about 180 beats per minute. This is two or three times faster than yours. Other vital organs, including the kidneys, intestines, brain, and liver (which makes red blood cells this week) are starting to work and will continue to develop throughout your pregnancy.

Can 10 weeks reveal the gender?

Although it is not yet possible to tell the sex of your baby by ultrasound, the genitals are beginning to form.

Is there any harm in going through an x-ray machine while pregnant?

Although the proven negative effects of prolonged cell phone use and passing through x-ray gates are insufficient, they are not recommended due to their possible negative effects on fetal tissue.
