Light periods or just spotting when your period is due.? I'm wondering because I was on the pill for about 3 months and I had normal flow periods . Last month it was normal flow with painful cramps. But this time it was way different. I haven't taken the mini pill for about a month? Could that be why or what could it be? It was pinkish red discharge and it had very little clots maybe the size of a pea. That's never happend before. I've had really bad head aches also....
