How To Cure Pain During Menstruation And Vaginal Swelling?

I am being treated for a very painful uti. I started bleeding the day I saw the Dr. Ths bleeding is definitely vaginal and not in the urine. My uti pain has gone away it seems but the menstrual pain and swelling is much more extreme than usual. I ve had a uterine oblation so usually I have about 36hrs of spotting with very minimal cramping during a period. Im taking tylenol and advil to manage the pain now. I was tested for chlymidia and gonorrhea and both came back negative. I feel if this is sti related my tests would have been positive at this point. Thoughts please. Thank you so much.
