A change in our normal schedule can make us forget routine things. It's happened to the best of us. Missing one pill increases your risk. Missing two and having sex without using a backup birth control method increases it even more.
Only thing to do now is to take a home pregnancy test. If you are not pregnant, remember in the future to always use a back up method in the event you have to catch up on your birth control pills.
