Im bit worried beacauseIt was my first time.... I actually started my first  brand of BCPs last july this year for the purpose of curing acne and secondly to prepare my body system taking pills for the upcoming contacts on november this year. And because of my acne getting worst, i undergo treatment and my dermatologist advised me to stop the pill... I stopped it the mid august till month of september, and september  i missed my period.  Then I again took the pills this october 21th, 5 days before my unexpected period. I am an irregular cycle of Period sometimes i don't have it for 3 months sometime i have it twice a month.  Im just confused. Is there any side effects that i took the pill before my period start? And should I still continue the pack for the next months? I am taking Diane 35 . i usually take it before bed everyday at the same time, and my doctor advice before , after I finish the first pack i will  start my second pack after 7th day. then do things the same for thext pack and so..... Is that correct? and Do I protected for unwanted pregnancy? Im pretty sure i will have my contact on the 3rd week of november, Am I safe if im taking the pill the my doctor adviced me?
