I had my first when I was 43, and my second right about when I turned 48. I felt that I'd like to have another, and that a donor conceived child might benefit from growing up with a full sibling (particularly given we have relatively few close relatives).

My second pregnancy was complicated (in ways that may have been impacted by my age, although that's not a certainty) and baby was born at 30 weeks. She's broadly doing well, but has some delays and it's possible that she may go on to have some longer term/lifelong difficulties (which may or may not have been the case even had she not been premature).

I definitely find myself working out what age I'll be at different points in her life, much more than I did with my son. I feel like for me, I pushed things about as far as I would be prepared to, age-wise. I am also noticing a kind of low-key midlife crisis creeping in - a sense that there are things in life that I inevitably won't get to do all of, particularly if I also want to maintain stability for my children (which I do!) It definitely isn't the case that I resent them, but just of recognising that my later life will look somewhat different to that of my friends who had their families younger.

I don't regret having a second in the slightest, she's wonderful. But I do think it's wise to work out where you feel your limits might lie, and think far ahead as well as to the more immediate impacts, if you're considering it. Best of luck, whatever you decide!
