I'm a 17 year old female. I'm sexually active. I'm on Camrese birth control staring 2 months ago and I take it everyday nonstop, no breaks, no periods. For the past 3 days I've noticed pale brown tissue/fiber strands in my urine. It's usually only 1 or 2 and it doesn't happen every time I pee. I've noticed it most recently within the few days but it's occurred before usually right after I have sex, but then it goes away and I never see it. I occasionally get a very very mild cramp/pressure in the pelvic area but I also have achy hips so the discomfort spreads out sometimes. Not too sure what's going on with my urine. Someone clarify?
