under 40 and have Endometrial Cancer

I am 30 years old and I just got dignaose with Endometrial Cancer. I have lot of questions and a lot of things I do not understand. I will be going to see a specialist on Oct 1st. To say I am scared is an understament. I found out on Wed since then I have hardley slept and have spent most of the time crying. Family and friends are there for me but they really do not know what I am going through. I love them for trying but I think I will go crazy if one more person says you will be fine when they know nothing about it. My husband and I had just decided we where ready for a family and where looking forwarded to it. I was having some trouble with my periods. My gyno put me on Provera to help stablize my periods. I was not really having any before that. I started the Provera on Aug 1 st 2010. I started my period on Aug 3rd and have been on it ever since. To make a long story short last week I had sever bleeding and blood clots. Wound up having to have a Dnc on friday. The Dr scraped 2.5" off my Utrues. He said everything looked good but they where going to check to make sure there was no underlineing problems. I went back the next Wed and got the results. They where not good and not what my gyno was expecting. He set me up with a specialist but I have to wait for over a week. I have been doing some reserach on line but I have not really found anything for somebody my age. Does anybody know if there is a chance I might still be able to have children? Is a hysterectomy the only option? Had anybody not had to have one? Please if you can answer any of these questions help me. I was also wondering if Endometrial Cancer is the same thing as Uterine Cancer?
