Not sure if will help you OP- because its not always a happy ending and my experience is different to many others.
Started TTC age 34 and after years, had the run around from GP who refused testing. Finally when D21 blood test was done, its was normal- and GP then wouldn't refer me to the fertility clinic!
After 4yrs TTC, when I finally did get pregnant naturally, I paid for the NIPT. Unfortunately it showed trisomy 13 (patau syndrome) and we chose TFMR.
I used to work abroad part of each year, so paid for private testing there. All was normal, tubes clear, and in fact my egg reserves were high for my age.
A year later pregnant again, but MC at 7 weeks.
Then IVF- pregnant, saw heartbeat at 8 weeks, then MC a week later
Told I'd be referred to the multiple MC clinic- waited 6mths, then told that I wasn't eligible- because the 1st pregnancy was TFMR and not a natural MC!
Another round of IVF and didn't get pregnant. The last consultant asked if I'd considered donor eggs- well no, it was the first anyone had mentioned it so I hadn't considered it. I looked into it, but by this stage I was 43.
I have a happy life, and a lovely husband- its just a different life to the one I'd always assumed I'd have.
