I remember getting mine when I was just 10 years old. And I only had about 4 my first year. They don't really become normal until after the first couple of years when they will regulate themselves. If it's hurting you too bad, talk to your parents and have them take you in.
For me I remember going through intense cramps and wanting to just die it hurt so bad, and I had to go on birthcontrol around 16 to help that, and it was treated with Midol and Pamprin before that, or even ibuprofen.
If you have more concerns,
PM me.
