Hello,
I want to know what kind of birth control are you using.. If you are using oc (ortho cy...), even though if you finish the green pill, you must start the new pack.. "the white" pills. Its the cycle of using the pill. Some people are varied but read the instruction on it.

I am not sure if you want your period or not, I know I hate it but there is an option you can do. When you get to the last pill for the first three weeks start a fresh pack of new pills. Basically replacing the "sugar pill week" with the first week in the new pack. By always being on the pill it will take your period away. I am not sure if you knew that or not. I would ask your doctor about it so they can explain it better (unless you already know).

The "skip your period" method usually works for me, but this time my body didn't take it. I started my "period" a week into the pack. I'm still taking my pills so I don't know when it will stop. I guess my body can only take so much playing around with hormones. Huh... I already took an early response test, so I hope i'm fine as far as pregnancy.
