I may never be able to have a baby naturally

So two days before Christmas my fiancé went to the doctors with what seemed to be a virus two weeks later we found out he had non hodgkins lymhoma (cancer ) and with cancer comes chemo after chemo he has a 30% chance of getting me pregnant it is the most devastating thing to ever happen to me I don't know what to do now I love him with all of my heart and that's all we wanted was to get married and have children on top of that my fiancé made most of the money my job pays half of what his paid and now he can't work I'm so stressed out more than I've ever been please pray over my family we've created a go fund me as wel if any one would like to help but prayers are the most important thing to me 💚 also I am not writing  this for anyone to feel bad for me or for the money I am just stressed and need someone other than family to talk to ! https://www.gofundme.com/non-hogkins-lymphoma
