hi i am 18 years old and have been on birth control for several months. i am sexually active with my boyfriend of 3 years and we have intercourse often. i recently began to spot only 1 and a half weeks after ending my period. i have been spotting for 12 days now. only a little bit of blood each day but enough to drive me insane. i went to the doctors and she said it might be stress, but 12 days feels quite dramatic to bleed from stress. any help? thank you!
