Hi, im 21 years old. I've been on the contraceptive pill (Levlan) for about 6 months and haven't had a period yet. I'm going to take my due period in one weeks time. I've had cramping for past week and just started to bleed a little. My boyfriend and i have unprotected sex quite often. I've taken regular pregnancy tests and they have all come back negative. The last one i took was about a week ago. What could this mean? Could i still be pregnant? I use to take this pill when i was younger and this never happened.
