Ah, you're back here OP.
Could you say why you've left this to 53?
Surely when you got to 38-40 ish you were thinking about having a child?
Was there not an opportunity then?
I do understand your desire for a child but I'm sorry to say it's supremely selfish. For a start, you're single so the child will never know a father. That's not ideal.
You probably underestimate hugely the sheer hard work of a baby, toddler and teenager.
You're doing something that may have been ok 15 years ago, but for whatever reason you chose not to then.
This is all about YOU - not the best interests of the child. So it's selfish.
If you have love to give to a child, look at fostering.
PPs said you're too old to adopt and that's for a reason.
A baby is not an 'accessory' to fill a gap in your life.
I also think you'll struggle to find a dr to treat you. It's different if you had frozen your eggs, had a partner to provide sperm and be the father, but you're on your own and may well be 55 before IVF worked even if you could access it.
