What is wrong with me? I have been on my period for 12 days. I was using a ultra tampon and two pads and it was full within 1 hour and when I changed it there was a giant blood clot about the size of a golf bal maybe a little bigger. The thing that is the worst is that a ultra tampon is full and leaked within a hour and I have to change it every hour. I'm 14 and this is the biggest period I  have ever had. The last 3 months I have had 6 periods. I use to only get my period every other month. Do you guys know what is wrong?
