The Size of Your Baby

At 10 weeks pregnant, your baby is about the size of a strawberry, measuring around 1.2 inches (3 cm) from crown to rump. However, this size is only an estimate because every baby grows at their own pace. By the end of this week, your baby will have doubled in size since your last period.

Baby’s Facial Features

Your baby’s facial features are becoming more distinct this week. Their eyes are moving closer together, their ears are moving to the sides of their head, and their nose is starting to take shape. Even their little tooth buds are forming behind their gums.

Baby’s Limbs

Your baby’s arms and legs are now fully formed, and their fingers and toes are no longer webbed. They can now bend their elbows and wrists, and their legs are starting to outgrow their arms.

Baby’s Organs

Your baby’s major organs, including the heart, lungs, liver, and kidneys, are all functioning and developing rapidly. In fact, their tiny heart is now fully formed, and you may even be able to hear it beating on an ultrasound.

Your Body Changes

As your baby grows, your body is also changing to make room for the little one. You may notice your waistline expanding, and your breasts may feel sore and tender. You may also experience nausea, fatigue, and mood swings as your hormones continue to fluctuate.

What to Expect at Your Doctor’s Appointment

If you haven’t already, you’ll likely have your first prenatal appointment this week. Your doctor will perform a comprehensive exam and may order blood tests or an ultrasound to check on your baby’s development. This is also a good time to discuss any questions or concerns you may have about your pregnancy.


In conclusion, at 10 weeks pregnant, your baby is growing and developing at an amazing pace. From their facial features to their tiny organs, every part of their body is working hard to prepare for life outside the womb. Take care of yourself, and enjoy this exciting time!
