I had to take prednisone by intramuscular injection until I was through my first trimester. That is longer than most, but my doctor was very cautious. I think at some point, I switched to suppositories. As I understand it, cancers that are hormone-sensitive are usually sensitive to estrogen compounds, but I'm not entirely sure.

I don't necessarily think the IVF is what may have played a part if hormones did at all...but I feel that they did in my gut. For example, if I had "the perfect storm" of things happening, such as genetic predisposition, recurrent trauma to the tongue, then add the hormones into the picture...who knows, but I hope we do know some day. Obviously, of all the women I know that were diagnosed and treated perinatally, I was the only one that I know of that had IVF and it was only one cycle. I know several women who have undergone several cycles. Plus, the meds they give depend on what is causing the infertility. In my case, I was ovulating fine, but I had a blocked tube its entrance due to left over tissue after my first pregnancy.
