I've been on the pill for about 2 months, the first month was fine. When i started taking my white pills i got my period on the 3rd pill. I was very emotional, cried a lot about anything. Once i started my next pack of pills i was fine. I am currently on my 5th white pill and still haven't started my period. I know I'm not pregnant, because i haven't had sex. So is there any way that you can stop having a period while taking all the pills?
