i used to have an irregular period but now it kinda comes every month. my last period was on the 28th of sept for at least 2 days of bad stomach cramps and gas then my period stopped for one day and started again for about 2 more. i've been sexually active recently but it's always been protected.

on the 20th of oct (yesterday) i went to the toilet and had a patch blood on my underwear like i had my period. after that day, at night i didn't have my period anymore? what's going on? %-)
