A couple of times a last month i had my period 2 weeks in a row and a week later because i kept forgetting to take birth control. After having it so many times I kept taking the pill until the next pack. During that time my breasts were sore for practically a whole month. Right now they aren't as sore, but somewhat. I decided to stop taking the pill on friday for the rest of the month because missing it that many times made me unregular, meaning i have no idea when i was supposed to get it or anything. Usually after missing the pill after 2 days i get my period soon after. However it's almost been a week after i stopped taking it and i still haven't got my period. I took the home pregnancy test 2 weeks ago, and today, still showing that i was not pregnant. However i still feel as if i am. Is it still possible i can be or what? Can it still take time to show up?
