april 7th thru 11th i got my period (it was normal) on the 13th i had unprotected sex and took the plan b pill less than 24 hrs after it happened. then on april 16th & 17th i again had unprotected sex but right after we were done on the 17th i got my period again and it lasted thru the 21st of april. (It was normal like the week before,but i never get it 2 weeks in a row) its very regular and starts on either the 6th or 7th of every month. May 6th and 7th past by with nothing. Around the 10th and 11th there was a little hint of pink but it never picked up. Should i be worried that Im pregnant or is this normal(ish) after taking plan b? PLEASE HELP SOMEONE!!!!!!!!!!
