You posted yesterday too, give it some time. You said your period was supposed to come this week in your last post. I think you're stressed out, try to relax. If you haven't been sexually active, you're not preg. Remember that stress can delay your period. If your period doesn't come by this week, go see your gyn. Good luck and try to be calm.
I can't see, both yesterday in your 2 posts and today in this one, that you've specified exactly when you took the patch off and exactly how late are you for your period. Please elaborate.
