After 40, signs of "pre-menopause" can begin in the form of delayed or absent ovulation at prior expected times, which allows constant production of ovarian estrogen, thickening the lining of the uterus, which can break down causing bleeding and even clots. If pregnancy is possible, obtain a serum HCG test to be certain. You might also ask your GYN MD about low dose oral bcp's.
