I have a 7 month old son and have been on birth control ever since I had him. My periods are ALWAYS on time and never late OR early. But the past few days, I've been having medium stomach cramps like I do when I'm on my period and I've been noticing pinkish blood when I go to the restroom. And as the days progress, the pinkish blood is becoming more heavy. But it's not red, like my period is. I have a week before my period is actually due, & I'm still on my pack of birth control pills.. So, I was worried that something is wrong with me, because this has NEVER happened to me before? Any Suggestions?????
