Hi, I think provera must have worked by now. please go for a pelvic ultrasound
scan as soon as possible to find out the cause of your bleeding , so that a specific treatment can be given to you. A local cause is more likely in your case e.g. a uterine polyp or a fibroid as this type of bleeding will not respond to medicines. I don't know your fertility status & any contraception
you are on but please also check your serum BhCG levels. As you are above 40 an endometrial biopsy
should have been performed before starting any treatment. You may add mefenamic acid
& tranexamic acid
to your prescription after discussing with your physician. May God help you.
