sensitive to touch Someone Please help

Anna
Ok so recently my stomach has felt really sensitive and I don't know what it could be it's so weird I've never felt this. 
Okay so I feel it the most when I'm laying down and my husband puts his arm on my stomach because that's how we always go to sleep him hugging me. But lately I can't take him hugging me because my stomach feels so sensitive, it doesn't hurt like bad pain but it feels really uncomfortable like sore or something like that. And most of the time I have to go pee as soon as he puts his arm around me. 
Has anybody else ever felt this???
