So, I had sex right after my period ended (oct 30) and it was unprotected. I got a little paranoid (even though I think he did not came inside me) and took the next choice pill the next day.. followed all the instructions. but now, six days later i am bleeding seems like a menstruation. What is this? is this going to be menstruation for the month of November? My next due date is 21/22. Am I going to get my period by then? I am kind of freaking out. help please.
