I am 34. I have had two failed cycles of IVF. It is likely that I won’t have babies of my own. But that’s kind of ok now because I know that I tried everything I could and it’s just that my life will take a slightly different
path to that which I had imagined.
I think you just need to ask yourself in ten years time, how will you feel if you don’t have children and you never know whether IVF would have worked because you couldn’t afford to try having spent all your savings/cash on a
wedding.
You will be with your FI for the rest of your life and will have so many occasions to celebrate your love for one another. I have been through the trauma of IVF and you really need to have everything working for you.
For what it’s worth, don’t leave yourselves too broke to try IVF. It’s a horrible process but if it works, surely it’s worth the financial, emotional and physical pain.
I say get married and have whatever ceremony you can afford given the potential costs of the next stage in your lives. There will always be another opportunity to renew your vows or celebrate becoming a family in the future. Good luck!
