Starting Birth Control pills (ever) a week before your period? - Instead of the first Sunday after?

I just got an rx for birth control pills, Seasonique. The whole reason for getting them is to avoid having my period for long lengths of time. My next period is due in 6 days. I would prefer NOT to get it. Instead of waiting for the first Sunday after my period, can I just start taking them now (today, right now), starting with the Tuesday pill. If there is any serious reason NOT to do this- what would that reason be?

The reason to wait until you get your period is to make absolutely sure you are not pregnant before you start taking the pill. If you have not had unprotected sex since your last period then it doesn't matter. You still may get your period or it may just be a little lighter. It will probably not disappear completely this first cycle because your uterine lining is already built up. You will shed some of it so be prepared. Waiting for after your period will also make it easier to judge if you are having any breakthrough bleeding while on the pills instead of it being "leftover" menstrual fluid from that cycle. (sorry that sounds gross)

You can start the pill today, you can start the pill the day your period starts or you can wait until the first Sunday after - it's totally up to you. However, there is no guarantee that even if you start taking the pill today, your period won't start anyway.
