it's possible that you ovulated late. BC pills are not %100 percent, plus they are even less effective if you do not take them at the same time every day. for instance if you normally take one at 8 am and one day you forgot until 10 pm, your "coverage" would be lower on the 10pm day. If you still get a neg pregnancy test and don't start your period in the next 3-4 days, see your doc. I would see your doc before you start your next pack if you haven't had your period yet for sure!
I'm pretty good at taking them at the same time everyday though. I am kind of new to birth control, could my body just be adjusting to it weird? I don't think I've been having any symptoms of pregnancy either. Would I have had my period in May if I were pregnant? Because it was a normal period. Since it's been seven weeks, I figure I would have symptoms by now, and I don't. I think I'm being paranoid. I'm sure stressing about this isn't helping the cause either.
