Yet another menstruation thread!
I'm 18 years old, turning 19 in a few months. I started menstruating five years ago. My cycle has
never been regular on its own (i.e., without the aid of birth control, when it achieves some sort of regularity). One year, I went from January to September without having a period (thankfully, that was before I was sexually active!) -- as you can imagine, this is annoying. I like to know my body works, from time to time! Anyway, I recently had a little epiphany: the year I got my period for the first time coincided with the year I started running. So - any correlation there, do you think?
I've mentioned it to my doctor several times in the past few years, and never any answer! I am thin, but I eat well, and am definitely in the healthy weight range for my height; also, my cycle has stayed weird when I have been both ten pounds lighter and ten pounds heavier than I am now. I run about 35-40 miles/week, but I don't think my mileage has anything to do with it being that it's varied over the years/months/weeks. Sooo, does anyone have a similar experience with their cycle? Does that seem like a semi-reasonable hypothesis?
