Choriocarcinoma

Has anyone ever had this?

I suffered a miscarriage 2 weeks ago after heavy bleeding and the doctors seeing a "blood clot" in my uterus. I should have been 8 weeks pregnant but was only measuring at 6.

After unsuccessfully completing the miscarriage naturally I went into the office for a D&S (similar to D&C, no anesthesia). My tissue pathology came back and I am now told I may have a rare form of "pregnancy cancer."

I am waiting to hear back from my doctor again tomorrow after more bloodwork but wondering if anyone has experienced this?
