It's normal. Before getting pregnant I was always in the mood for sex and during the first trimester it got worse but now I want to slap him if he even tries. I feel bad, and when we do have sex, it hurts and I am uncomfortable and it's not pleasurable so like valarie21 said, I am just thinking to myself, "hurry up" this is not fun.
Definitely normal. I NEVER want to have sex, but I do anyways to keep my husband satisfied & the WHOLE time I'm thinking in my head "hurry up"
