So i took plan b on the 12th of july and my period was due on the 15th of july. My period however i guess started the next day after taking the pill. It was a weird period. Some times lighter and some times heavier. If i had a period after the plan b and like literally was leaking blood.. i couldnt be pregnant right? Im also one day late for my period w no pms other than a few hormonal pimples.
