Hi, I miss my periods sometimes 1 month, sometimes 2 months in a row. I am not sexually active and I don't over exercise and I am not under or over weight. I don't exercise all that often, I'm not on birth control and I don't think I am stressed. Is there another reason why i would be skipping so many periods in a row? I haven't been to a gynecologist in about 8 years and I can't afford to go.
