Birth control: Ortho Tri-Cyclen?!

I just started Ortho Tri-Cyclen birth control yesterday after I visited my doctor!. My last period was from May 28th through June 3rd and I want to change it to around the 9th through the 15th of every month!. He suggested I started with the blue pills and take the full two weeks of those, then to toss that pack and start fresh with another one so that I'm on five weeks of active pills and I would have my period when I wanted!. He warned I might have an extra one somewhere in the middle, though!. My question is, will this change my period like I want and when will the birth control take effect since I will be starting with blue pills and won't take any white ones until the third week!? Thanks!Www@Answer-Health@Com
