Stitch pain on sides

SKYLAR LINVILLE MISSING

I'm 15wks 3 days and past 2 days have started noticing the achy painful stitch feelings on the sides of my stomach especially when getting up from a laying position. OUCH! it stops me dead in my tracks rubbing my belly until it passes. Feels like when you run hard and your sides ache. Anyone else have these stretchy pains.
