What is the size of my baby during week 15?

During week 15, your baby is about the size of an apple. At this point, your baby can sense light and likely to change position - moving away from any light pointed directly on your belly. Although your baby is moving a lot you're not likely to feel its movements yet. Soon enough those sudden hunger pangs and flutters that feel like butterflies could be your baby's tiny fists and feet moving!
