Sex drive gone

I’m 12 weeks pregnant today and I haven’t felt like having sex in a month and a half... I don’t feel like it and I’m always in the no touchy mood. No kiss, no touch, heck I don’t really want to be looked at. I have no idea why... I try to have sex to please my fiancé and it’s awful. I feel like he’s touching everything and it feels too tight. TMI, and my vagina feels raw immediately after we start and I’m wet and we use lube, but it doesn’t help... someone please tell me this goes away... I feel awful for me and him. I want to please him and I just feel so bad doing it that it’s not enjoyable. It not him. I don’t want to with anyone. I honest to God could careless is we did it at all at this point. It’s driving me crazy and I feel like crap bc I don’t think I should be this way... anyone else experienced this? Will it go away? Is it normal?
