help about getting my eggs frozen

Shelz
I Had an ectopic pregnancy and lost my tube my ovary remains but 8 year ago I had my other ovary and tube removed. I have pushed so many times to get my eggs frozen but I don't meet the criteria the criteria being cancer paitents and I don't have the money to go private I don't know who to turn to I have asked my doctor and gynocologist to see if I can get it done on the NHS I'm scared I will lose my remaining ovary I'm looking for some advice
