Your Baby This Week
Bone Development
At week 15, your baby’s skeleton continues to develop and strengthen. The bones are becoming more defined, while the joints allow the arms and legs to move more freely.
Although the bones are still developing, the skeleton is becoming increasingly structured.
Hearing Development
The structures of the ears continue developing and moving toward their proper positions. The inner ear is also developing, helping prepare your baby for hearing later in pregnancy.
Facial Features
Your baby’s facial features are becoming more recognizable. The eyes, ears, nose, and mouth continue changing as the face develops.
Stronger Bones & Growing Fast
Your baby is about the size of an apple. The skeleton is developing rapidly while the muscles and joints allow increasingly coordinated movements.
Your Body This Week
Your body continues adapting as the second trimester progresses.
Growing Belly
Your uterus continues expanding, and your pregnancy bump may become increasingly noticeable.
More Energy
Many people experience increased energy during the second trimester as early pregnancy symptoms begin to improve.
Increased Appetite
As nausea decreases, your appetite may increase. Focus on nutritious foods rather than simply increasing portion sizes.
Nasal Changes
Increased blood flow and hormonal changes can sometimes cause nasal congestion or occasional nosebleeds during pregnancy.
