I’m torn

So I need some impartial advice.

I got engaged sept 2022.
Booked my wedding for March 24.
Since booking my wedding (paying a lot in deposits) my family have declined in health.. and it looks very variable if they will now make it…. They all say yess.. but depends on the time. i have a small family and a small friendship group.
I understand my friends and my family all have lots of different things going on but there doesn't feel a huge amount of interest although I am fully aware that to everyone else it is.. one day. That’s it.
Me and my husband played with the idea of eloping and having a register office at home.. but when I imagined a wedding a never visualised it. I can totally see why you would though.. I just didn’t get the feels the same way I felt about my venue.
However aside from the the fact that I am constantly worried if my family would make it, I’ve also started to become focused around wanting a baby. if I had a baby and wedding after I don’t want to write my family off but I can’t see there health getting any better and my main thing I wanted is the photo book of all your loved ones in one place.
Soo.. ringing the venue just to talk options.. they offer you can cancel and lose your money..,unless it gets resold.. or moving the date to nov 23. After they said .. about moving the date to end of October or nov 23 I did feel better. it’s closer in terms of family and would also move trying for a baby closer.
However… I now don’t know what to do.. as within the last month.. My two best friends have spoken about trying for a baby (not pregnant currently) Giving the wedding would be 10 months away.. I feel really torn.. do I plan a wedding around hypothetical babies.. do I risk my best friends not being there ..?
