Women with a low body weight, are frequently under high stress, or in perimenopause tend to have irregular periods. These women have very low estrogen production, so the body has trouble communicating to the ovaries that eggs need to be released, and ovulation does not take place.
Now I've seemed to miss my period but I feel bloated and have cramps as if it were coming. I am 46, have had symptoms of perimenopause, and am wondering...is this a common problem, that is to feel this cramping and bloating without a period? I just had my yearly pelvic exam two months ago and it was normal.
