question: I started low dose birth control on Friday May 4th.  It was the first day I had blood spotting for my expected menstrual cycle.  I have taken the pill every day since at almost the exact same time. And I have not had sex or any physical contact with any men at all during this time.My period was unusually light for an entire week.  I thought maybe this was a result of the pill.  But now it is 15 days later and my period is still going.  Today was the heaviest day yet.  Can this be because of the pill?  I should probably mention that I am overweight (5ft 3.5 inches 209 lb).  I have an appointment with my doctor on 5/30 but now I'm getting concerned.
