I'm 44 and been bleeding for a month straight for the past 4 months what could be wrong?

Please see your doc: There are many things that could be causing this. However if you have truly been bleeding everyday for 4 months this needs a thorough exam and lab work to determine the cause.

Menorrhagia: Menorrhagia, or bleeding in between cycles, or heavy bleeding can reflect an imbalance between estrogen and progesterone secretion, anovulatory menstrual cycles, spontaneous miscarriage after undiagnosed pregnancy, uterine cancer, or a bleeding disorder. I would seek medical attention immediately, and have your physician o lab work and an endometrial biopsy to diagnose the problem.
