Will birth control pills regulate my periods?

I've been off of the pill since June. I've been irregular. I just moved and now I'm not getting my period. My last period was for 2 days in September. I'm not pregnant either. I now have birth control pills to take. When should I take them and will it make a difference?...

So many questions... so many answers.

Okay, here I go. I am 19 years old, and lost my v-card last September. I am new at this thing called sex. I have so many questions that I am scared to ask... my parents would freak out if they even knew that I have had sex. so I am turning to you for advice. I hope that I do this right, and that you can answer my questions. • Is it supposed to hurt? I do not enjoy sex at all......
