so i had sex back in july.. i ended up having to take plan b the next day be cause of a complication with the condom. i had already had my period for the month of july. and then i had another when the pharmacist told me i would because of the pill. with that i had to periods in july. i didnt have one in august and now its already the 7th of september and i havnt had one and im stressing a lot because of what my school is its very bad to be prego around this job because of gasses . so i was just wondering if anyone else had this problem with taking plan b if it really messes up your cycle or what.. thanks=)
