i was on the minigynon 30 for about 5 years & decided since july 2011 to stop taking them, my period came on july 13, 2011 & a day after my period i had unprotected sex & my boyfriend come inside me, we had unprotected sex again on july 29, 2011 & he did the same, i took a minigynon 30 right after, one in the morning & another in the night, i have taken around 8 of the pills within 5 days, my period was due for august 5, 2011 & it has'nt come, i have been having period like pains, but it has not come, i did two pregnancy test which shows negative but is it possible that i could still be pregnant or should i still watch out for my period?, im just hoping that the pills did something to my hormone causing this delay. your advice please
