I started my period when I was ten. I am about to be 15 and they are still about 1 1/2 to 2 months apart. I was just wondering if there might be a reason why that is happening. Like, something about my ovaries, or anything else that coud be causing the late periods. Please Help because I don't know if it is healthy or not. And if you know why they aren't regular, can you make some suggestions about how I can get them regular?
