I am a 21 year old female and ive been spotting for 3 weeks. im also on birth control for 8 months and have regular time to time spotting. But for 3 weeks straight ive had spotting everyday of light red, brown, pink and some line clotting barely. the spotting is sometimes even just a smear but its been happening for 3 weeks. ive made an appointment already but seeing if i can get some answers before hand. ive taken pregnancy test atleast 5 times a week and all negative. and today aslo, negative.
