What if you missed 2 pills in a row should you just stop completely and wait to start over again?

It depends what kind of BC you were using. If you still have the paper that comes with each package, it will tell you in there. If not, as long as it's only been 2 pills you can usually just take those and resume as normal. You also may get your period or spot for days until your next period. Trust me, two months of that, and now I take my pill religously.
