(TMI) 6 weeks pregnant & feeling discomfort down there.

For the past days I've been feeling weird down in my vigina lately....today i had sex with my SO and when he went in it was uncomfortable, it didn't hurt but it bugged me. After he was done i felt as if my vigina was heavy. I felt inside and its really soft idk how to explain it..but idk what's going on....any ideas?

By the way i think i have an UTI because when i pee its uncomfortable. But does an UTI make viginas feel heavy and uncomfortable?
