I have a 7 month old son and have been on birth control ever since I had him. I take them religiously and have ALWAYS had my period on time...never late/early. But the past few days, I've noticed pinkish blood and medium stomach cramps, like period cramps.. And as the days progress, the pinkish blood is becoming more heavier.. I'm worried something is wrong with me? .... I'm still on my pack of birth control pills and I have a week left until my period is actually due! What could this be?? Any suggestions?
