Hi, I was wondering if it would be a problem to start a new pack of pills on Monday (after period) for someone that is usually a Sunday pill starter. I've been on birth control for over 6 years and am a little concerned because I had sex on Friday (during inactive pill time, but was not spotting/bleeding from menstruation) and completely forgot to buy a new pack of pills, and have to wait until Monday to do so. Should I go ahead and take two pills on Monday, or should I take Plan B on Monday instead? Please help! Thanks
