Okay, you should've started a new pack. But since you didn't, you should have been using protection girl!! Even if you had missed three pills and then started a new pack you would have needed to use back-up protection to prevent pregnancy. You could be pregnant. You'll have to wait to see if you miss your period and test if you do.
If that would happen again (missing three pills in a row), start a new pack and use a back-up method, or just don't have sex for at least a week until it gets back in your system. Remember, each pill pack comes with directions on what to do if you miss a pill, two or three.
I hope everything works out for you!
