You're most likely fine. It is probably just your period. ANY bleeding during the pill free week is considered withdrawal bleeding. But, I know the pills say wait 7 days, but I would always suggest a month. My boyfriend and I use condoms as well to be extra safe. If you are really worried, take a pregnancy test. But the bleeding and cramps are most likely your period coming on, or just a really light one. My first period on the pill was very heavy, but everyone now starts off with some spotting, then goes to just having to use about a pad a day. They are very light and nothing like before. Good luck.
You should be fine. It can take a little while to get your periods regular when starting a birth control pill. I would however encourage you to keep track of your cycle for a few months to make sure you are not having any break throw bleeding. If you were, you would need to see your doctor for a medication change.
