Provera, cramping, gushing?

looking4advice

Quick update - I went to the gyno because I had a never ending period. I am 51 years old and figure that I am probably in perimenopause. (Three years ago I had a ultrasound/transvaginal ultrasound and it did show that I had a couple of fibroids and a polyp - I ended up having an endometrial biopsy at the that time.) Back to now - Gyno decided to put me on provera for 12 days and then get a ultrasound/transvaginal ultrasound. I took my last provera this past Saturday. I did still have bleeding the whole time I was on provera but got more of a regular period on Monday. Then Monday night I had terrible cramps and pressure "down there" but no bleeding. It got worse and worse all through the night Monday and about 4 in the morning on Tuesday I got up to go to the bathroom and the blood just gushed out - very thick, very clotty and ALOT! Good news was that the cramping eased a little. Then about an hour later I started feeling miserable again with the terrible cramps and pressure but again there was no bleeding. I eventually called the dr. office and they told me this is normal. Then right after I hung up and went to the bathroom there was such a scary amount of blood and clots but the cramping went away. It then happened again - the cramps, pressure, no bleeding then the gushing. Has anyone else had this problem with provera? Any thoughts on this would be helpful. Thanks.
