I'm 15 years old, and I'm almost 16 years old, I'm 217 pounds, I haven't had a normal period since I was in grade 7, But I did was off for over a year, and back in November, I came on for a week. Then, December, I was on for two weeks (light) and in January, I was on for two weeks, and half (two weeks light, and one week light/heavy) I finally went to the doctor about my periods, they put me on Birth Control to regulate, my periods. I took my three weeks, and now i'm on the white pills, in the 28 pack, which I don't need to take for sugar pills. I came on my period on Friday, (I had light cramping, fgured it was something i ate) but I came on. I've had crammps, and bad stomach, since Friday. I'm on VERY heavy. Like, it's been the worse I've ever been on. I'm assuming, the pills made me come on, I don't know if I should be worried if it's heavy or not. All my family as heavy periods. My doctor said, if I am on over a week, it's where I am ottnot regular. But, even when I go to pee, blood drips down in the toilet, that's normal, i'm assuming. But, shoudl I be worried, where I still have cramping, and i have heavy bleedng on period? thanks.
