Actually, I know that from firsthand experience. In
2000 my doc treated my bleeding with that and it got worse and in
2004, I was given a depo shot, which I think is mainly progesterone, and I was already bleeding and it got much, much worse and I had my procedure done early. That was supposed to thin my endometrium beforehand, but all it did is cause a major flooding incident.
Anyhow, if anyone knows the answer to this, please let me know and where I might pull the information up from.
