during the last three months I have been with two different guys, one of them is now my boyfriend. during the last days I have felt a bit sick, i have started bleeding, even though I'm on the pill and my period isn't due before next week. At one point i felt really dizzy and nauseous and that is when the bleeding started, the bleeding hasn't stopped but I don't feel dizzy and nauseous anymore. I have also had something that could resemble menstrualcramps as of this morning. I can't recall that i have missed any of my pills, but I have heard that even though you get your period and take the pills you could end up pregnant.. is it true? Could I be pregnant?
