Vaginal dryness during pregnancy normal?

I’m 36 weeks now and sometime around my second trimester I started to become less and less wet down there and now it’s just so dry down there & swollen me and my fiancé haven’t been able to have sex for like four months because of the pain. I still have discharge but it’s not the same as before I got pregnant like it’s thicker now. Before pregnancy I was like almost constantly wet down there and my discharge was very watery. Is this something I need to bring up to my doctor or will it go back after I give birth? I’ve had lots of pelvic exams done this pregnancy and they are painful doctor always tells me I’m just swollen.
