So ive had brown/old blood for two weeks straight now after my missed period. Ive taken multiple pregnancy tests and had a urine STD test that came back all negative(tested for chlamydia,ghonnorhea, and trichomoniasis, pregnancy...all negative). I have the copper IUD and have been prone to yeast infections within the last 2 months (having 1 actual period after the first yeast infection, and then had another one after that and feel like im gettint ANOTHER one) and now i have a UTI. I am sexually active with 1 man and only been with him for the last 3 months and hes only been with me. What could be the cause of all this considering all my tests have been negative?? I do have a family history of PCOS and endometriosis.. Im going to call my gyno tomorrow and see if i can get an appointment asap to do all of the testing again and possibly an ultrasound to see if ive got any abnormalities or cysts. Anyone else experience similarities?? Im getting worried now... my period tried to start and i had actual red blood for just barely a few hours but went back to the brown discharge. I feel helpless and miserable and gross after getting yeast infection after yeast infection and now a damn UTI. I always pee after sex to try to prevent it.
