I understand that a typical cycle is 28 days from beginning to end. Mine has been that I bleed or "have my period" every 14 days. It has been this way for 8 months. I am 32, I have had several children over the years. I have had a history of ovarian cysts, cervical cancer, and andemetriosis. My mother had uterine cancer and had to have a hysterectomy in her 30's. I have been very irritable, have had lack of sleep, hot flashes, night sweats, headaches. Is it possible that I am headed for early menopause? I had a pap within 10 months and it was normal. I do not take the pill as I have a tubal ligation (clamps on my tubes for 5 years now).
