I Ended my period Last Thursday 2 Days later condom broke took plan B. next week Started getting a light light period Saturday Sunday it got a tiny bit more blood I put a tampon in because I hate pads but it hurt it feels very uncomfortable which is different for me Monday was the same and now its Tuesday and its light light again. My periods are usually very very heavy but not this time. My right boob is sore it hurts to lay on it and my left doesn't hurt as much. Since its light we "did it" and after I felt sick and threw up a bit but nothing to big. I'm not suppose to get my period for another 3-4 weeks but I got this? I don't know why my body is doing this my periods are regular. Any answers?
