I'm 23, have two kids. My periods are usually completely predictable. Not this time. It started on time, but was sooo heavy I was going through a tampon an hour. I also was having large clots coming out even when I had tampons in. On day six, it changed from blood and clots to brown discharge, kinda like old blood, maybe? I had no cramping, just an uncomfortable feeling down there. Now it's day ten and its still going on. I don't know what's going on! Anyone else experienced this, and what did it end up being?
