Birth Control and Delaying period??!

Nat

I am on Tri Lo Sprintec and I decided to start a new pack of pills on the Sunday I was suppose to start my placebo pills to delay my period by a week. I wanted to know if any of you guys have experience in this or if I a still protected from pregnancy since I started the active pills a week early. Or will I be protected from pregnancy the following month after I get my new period of wik I need to use protection as well. I am asking for a friend. ( I should mention this BC is the generic of Ortho Tri Cyclen ) any advice you ladies can give I will be 100% grateful.
