Hi, I am a 27 yo lady and I didn't menstruate for 9months, but I started menstruating again last month, after which i noticed blood spotting when i clean up after using the toilet and on my white pant once. this went on for some days and then i noticed the read spotting changed to dark brown, i noticed that just once. i have gone to see the gp and i tested negative to pregnancy test. also, i have boil in my private part and on my breast, i am presently taking medication for this. i have a burning sensation in my private part as well, to which i am applying a carnesten cream. also, i have been diagonised with fibroid, the size and location has not been determined. I am concerned about the spotting, what could be wrong.
