I just stopped taking birth control after about a year of taking it a little over a month ago and a week later after stopping taking it i had what was like a normal period. well, my period is now due again & i’m currently 3 days late. i took a pregnancy test the day i was due for my period and it came out negative. my beasts have been sore only in the nipple area for like a week now.. idk what that really means either. is it normal to be late after stopping birth control? if so how long?
