Pain during/after sex?

I’m 22 weeks today. We haven’t had sex in a while (two or three weeks) and tonight we did. It started out as just uncomfortable, but for obvious reasons; big belly, tired, achy hips/back... Then as we started getting into it, I began experiencing a burning like pain that felt like it was near the urethra area? But maybe not? I don’t know, it was just painful altogether. Anyone else felt similar? I’m afraid it may be a UTI but I’ve also seen where women experience painful sex during pregnancy. My first baby sex was fantastic but this time it’s just been “blah whatever” until tonight when this happened.
