I have been on the Ortho Evra birth control patch for a few months. I had my first regular period since I first switched from the pill to the patch about ten days ago during my off week. The Sunday after my period started, I put my patch back on. In the directions that come with the patch, it says one should use auxiliary contraceptives like condoms or spermicide for the first seven days of wearing it (after your off week). However, the Ortho Evra patch claims to stop ovulation altogether, so what's the point of this directive? More importantly, what risk did I take by having unprotected sex on the seventh day of wearing my patch again? Is there a chance I am pregnant? Thank you.
