Hi, I'm 15 and I started my period about a year and a half ago. I had my period every month and it lasted for about 8 days usually. For the past two months, I've had INCREDIBLY large clots passing and very long cycles. My cycle seems to be never ending at this point. My last two periods have lasted for 25+ days with maybe a week and a half between them. I started seeing small clots (smaller than a nickel), but then they began to grow as the cycle went on. I have to change pads so often because of the excessive bleeding and giant clots that are passing. The clots from my period currently have been as big as golf ball or larger. I pass many within an hour. When I sit down I can feel the clot trying to come out and as I stand up I can feel relief in my lower back (sorry for that gross scene). I don't know what to do, I keep telling my mom about it and she says it's fine but I'm worried.
