Ortho Tri-Cyclen - I started using this pill and I started my period during the first-second week I?

As long as you're taking them at the same time everyday, you don't have much to worry about. You will have weird bleeding while you're body is getting used to it. What you have when you're on active pills isn't your period, its break thru bleeding. Birth control pills decrease the lining of the uterus decreases, and this is what you "bleed" so it could be that break thru bleeding was all you have for this month. You don't have to start at a particular time on the placebo pills, so you still have time too.
