many things can cause irregular periods even in women who are usually regular. you don't say what your age is but perimenopause is heralded by getting irregular periods. with perimenopause the irregularity is caused by the production of less estrogen by your ovaries. in women too young for menopause irregular periods can be caused by all of these things and more: excessive weight loss eating disorders emotional stress medications problems with pelvic organs if you've always had regular periods that now are becoming irregular why not make an appointment with your gynecologist? he or she is in the best position to assess why your cycle may have become irregular. and remember: you can still become pregnant even if your periods are irregular. so continue to practice birth control if pregnancy is not your goal! best wishes to you!
what would be the reasoning for my "cycle" to skip 1 month & then next be only 3-4 days then the next last for 2 weeks?
