Take the pills like you normally would if you weren't having your period at the wrong time. The pill won't leave you unproected during the week after your period because BC works by keeping your body from releasing an egg at all. No egg, no way to get pregnant. However, if it makes you feel better to start a new pack, it won't hurt you (which is only true with monophasic BCs like Lutera, not triphasic like ortho tricyclen) you will just be delaying your next period. DO NOT switch to the green pills just because you are bleeding, this can cause the accidental release of an egg and increase your risk of pregnancy.
