For 2 yrs he told me all I needed was the 2mg estradiol, since I was not having a reg period. I seemed fine until I recently started passing dry blood clots when I jog. He added the Medroxypr as 2.5mg. Now I have been heavily flowing with many clots since 3 days after begining the medroxypr. It has been about 22 days of heavy flow. Should I be concerned? I do have headaches as well. Normal extremely healthy person.
