I think most things have already been said by others and I think you should consider all the advice given.
You don’t state whether or not you already have any children, if you don’t then I can see why you may have more of an urge.
I’m not going to say it’s too old, it’s a personal choice. For me, yes it would be too old. I’m 38 and expecting number 4 (first with a new partner), and for me, my cut off for trying would have been 40. Pregnancy so far has not been any harder than it was in my 20’s, but I do consider myself fairly fit and active and I am still only in the early days of it!
I found the whole ttc process far far more difficult than I did with my first 3 dc when I was in my 20’s and early 30’s. It took 16 months and 4 miscarriages before falling with this one.
I had various tests with a fertility specialist who told me I was pushing for time if I wanted to go the ivf route.
Thankfully we didn’t need that help, but from the information she gave me, had I chosen to go ivf they’d would have heavily encouraged me to use donor eggs rather than my own.
It was clear after the 4 miscarriages that my own eggs weren’t of great quality anymore. I’m only 8+3 now so only time will tell if this baby is healthy with no chromosome issues.
I would contact some private fertility companies and at least get a consultation and perhaps some initial tests carried out so you know what your options are.
I wish you all the best but please prepare yourself for the fact this may not ever have a happy outcome. Xx
