Anyone else with this pain?

Ok here it goes, I'll try to describe it. I get this annoying kinda sharp cramp pain right below my breast where my tummy starts. Everytime I lay on either of my sides it gets so uncomfortable that it frustrates me cause I'll be so tired but I spend my nights tossing and turning cause of it. Idk if I need more pillows and idk what it is. I only have one flabby body pillow so im guessing it's that. The only comfy position is on my back and I know that's a big no no but sometimes I slip only because that's the only comfortable way I can sleep. It kinda feels like the kind of cramp you get if you drink too much water or eat too much food. It's not a bad type of cramp. It's just annoying. Help pls
