Pelvic pain and lots of cm? UTI?

So at lunch time today I suddenly got a really sharp pain in my pelvic area. As the day has progressed it’s gotten worse. I don’t generally have a period (and I’m not on BC) but my period is a week late. My last period was induced with Provera and I’m actually due to take my 3rd round of Provera today. But I can’t understand what this sharp pain is. It’s almost like my bladder feels full but it doesn’t hurt to pee but my pelvic muscles hurt and I feel cramps and the cramps go to my butt muscles. The past few days I’ve had really heavy CM that’s clear and stringy. What do I do? Is it a UTI? Should I see a doctor?
