Uterus stretching?

Macayla • Mommy to two lovely children 💕 and daycare teacher of 9 wild toddlers 😬
Does anybody else feel sharp pains in their lower abdomen? My baby hasn't been moving very much the past few days plus I've had this feeling and it's enough to really freak me out. It feels a little bit like knives and it doesnt last long. It usually goes away when I sit down &ive had them before but not so bad. Anybody else have this and is it normal?
