Oh, please. 37 is far from old.
I had an amazingly incident free, healthy twin pregnancy and gave birth when I was 38.5. I actually felt pretty amazing/glowing whilst pregnant and it was one of the happiest times of my life.
I had an emergency section, as Twin 1 decided to go breech. It was a straightforward procedure, although I lost a lot of blood, and the recovery was without incident and I just got on with it (my husband decided to disappear, so it was just me in the early days and, whilst he popped back up, I left him when the girls were 4 or 5 months old).
Nothing wrong with either baby and the girls are now 5.5. They're both Neurodivergent, as am I, but that's nowt to do with my age.
I already had some chronic health conditions, osteoarthritis, degenerative spine and disc disease, Fibromyalgia and Fibroids, BUT I had my 2 beautiful girls in spite of all this, which is a miracle, as was told I wouldn't ever carry babies (multiple MCs).
We have a quite basic, okay quality of life, despite me having physical health issues and, honestly, I've needed a lot of energy solo parenting hyper ND twins with zero support.
So, yeah, maybe being older does carry some risks and maybe is a worry when you had child(ren) younger, bit I can only speak from my own meandering experience.
Good luck x
