okay - first you need to understand that periods can change especially as you get older with more stress more sex ect. the brown discharge is probably old blood and seeing as you said it had been 12 days that may explain why it is brown and spotting - and it can last several days after your period. pulling out is not a guarantee method of birth control (not that i am saying anything else is guaranteed) you maybe pregnant some women have their first period after conceiving. ovarian cyst are also maybe a possibility and any chance of toxic shock syndrome? but chances are it is just an abnormal period. if it continues or you start to have pain or new symptoms the only safe bet is to call your obgyn. good luck!
really irregular period lasting 12days first was light and past days has been brownish. why would it last so long? never has before. also its very light usually heavy period or just light on the last day. no change in routine tho am sexually active he pulls out is there a chance i could be pregnant? also my period came early and these last couple of days has been more like spotting any suggestions? no insurance right now so any advice would help. should i wait it out or buy a pg test?
