15 weeks pregnant: Fast facts
Around 4 inches long and weighing 2 1/2 oz, your baby is about the size of an apple.
Your baby can sense light and may even move if you shine a light at your tummy. Amniotic fluid is moving through your little one's nose, helping air sacs in the lungs start to develop.
As your baby and belly get bigger, it's a good idea to start sleeping on your side. The weight of your uterus can restrict blood flow if you sleep on your back. If you wake up on your back, no worries! Just shift to your side.
Pregnancy hormones relax your digestive tract, which can lead to gas and bloating. Certain foods can make it worse. To reduce symptoms, experiment with your diet and talk to your doctor if you can't find relief.
Is your bump obvious now? If not, don't worry. You'll probably start showing in the next few weeks.
