i am just ending my third month on the pill. this is the first birth control i have been on. in the past month and a half i have started being sexually active. i use condoms and take the pill everyday at 6. i didnt get breakthrough bleeding until about halfway into the 2nd month. it lasts about a couple days, and comes randomely. i never know what is my period or not. people have said that its not normal after the third or fourth month to have breakthrough bleeding, could it be a sign of pregnancy? or is it just me getting used to the pill? and how long will i be having breakthrough bleeing?
