Still try for what we want the most??

I’ve been with my husband for 4 years and ever since I met him, we both knew we were made for each other. When we first got together, he told me his medical history that involved lots of chemo therapy. Everything has been great with his health up until last year. Last April, he started having heart problems and without getting too technical, he hasn’t been getting better through everything the doctors suggested. Today, we went to an appointment and yet it is still early to tell for sure but they are possibly looking at a heart transplant within the next year or two. I’m scared to death of this. My best friend passed away last year after battling heart problems and she eventually got a heart transplant but passed away 4 years after the transplant. I don’t want to let this hold us back from anything and therefore been trying to conceive (with the help of a donor because we don’t want any of his health problems passed down) but I question now even trying to conceive. I know I will always have my family and his family plus the donor and his family to help with anything I need. I know that my husband wants to be a dad more than anything in the world. He would

be a fantastic dad and love the child more than anything. But knowing the child could potentially grow up without a dad, is it still a good idea to try? Has anyone been through something like this and the outcome has been a positive one? I’m trying to remain positive but the uncertainties of the future are really weighing on my current plans for a baby. I am 28 and my husband is 33 if that matters at all. I apologize for the long post but thank you to those who read this as I can’t talk to many people about this
