0 sex drive!

I'm almost 15 weeks and I have absolutely no sex drive. I try having sex with my SO every few days to keep him satisfied but it doesn't help with anything. I can't just sit on the couch or lay down for bed with out him touching on me or pushing on me. I've told him that I just don't feel like it especially if I'm having some cramps or just don't feel well. It's really getting under my skin! I can't stand it at all. Okay, rant done.
