I took Plan B and not long after got a light brown period that lasted about five days (which I know is normal). But what about after? I'm experiencing cramps here and there, my breasts are tender still and when I go to the bathroom for bowel movements it's like I have stomach bug with the way it comes out (which only usually happens when I'm ON my period). I'll also feel a little nausea. Are these symptoms normal even after the five day period?
