I don't know much about this, what did your Dr say?
You will be able to have children. You will proabably need help though. I have PCOS and endo. I was on Metformin for three months and I got pregnant. I am 7w 3d today. Everything is going well so far. Good Luck!
Yes, you may be able to conceive, but like the other poster said, you may need fertility treatments. I know its scary to find out that kind of diagnoses. To find others in similar situations, you might try posting in the Ovarian Cancer forum. (Most of us there aren't diagnosed with cancer, but are waiting around for surgery and such to be diagnosed.) You will find lots of support there :)
