Hi! So I'm about to be 18 years old next week but I have an issue. I started my period 9 days ago and it usually ends on either the 5th, 6th, or 7th day. So it kinda hasm me worried. My period did stop tho for half a day on the 5th day, and I had protected sex. But the next day, I woke up to what seemed to be my period, or maybe even heavy spotting. And it only lasted half the day, and then the next day I woke up to it again, and now today, it happened again. I have been taking birth control pills for around 9 months now. But could there be something wrong? It's just very odd to me.
