Cramping and Tightening- 17 weeks

Samantha

Just had sex because I'm a horrible wife if I don't put out for my husband.

Well, it hurt, and now my uterus feels super tight, and I'm cramping in my lower back. No blood, but everything just feels off. Anyone have any experience with this and can reassure me? I didn't want to have sex in the first damn place, but the guilt isn't worth saying no.
