What are these signs of?

I’ve been having pressure pain in my lower back and in my pelvic area. If I cough or sneeze or anything like that I get a sharp pain down there. Also, TMI but I’ve had weird diarrhea for the past 2 or 3 days and I’ve felt really nauseous at times. I don’t think it’s anything serious but I’m curious to know what it could be.

Any ideas?
