This is my 3rd month being on the Marvelon birth control pill, and normally my cycle comes and goes with no hitches or confusion. However, this past month I have been a bit worse about taking it on time, though I have never forgotten by a full day (at most, I have forgotten by 4 hours). This month I was also put on iron pills and stool softeners to help with my anemia, which has resulted in some bouts of diarrhea. I know that both of these situations can lower the protection which birth control provides, so everytime that my boyfriend and I have had intercourse, we have used condoms as well. The condoms have never broken, or fallen off.
Yet, being the paranoid person that I am, I am terrified that my pills have lost their effectiveness. On Monday, exactly a week before my expected period, I had bleeding and abdominal cramps. It soaked through my pad and onto my bed! I had moderate bleeding on Tuesday, but by Wednesday and today the bleeding had become light. The abdominal pains are still killing me though.
Could this be from taking my pill that little bit late? Or from the iron supplements? Or could it be an implantation bleed?
On the last birth control pill I was on, I had breakthrough bleeding for 3 weeks straight. But I have never had bleeding before on Marvelon. I plan to take a hpt in one week, on the day of my expected period.
