I was similar - fell pregnant early 30s the month I stopped contraceptives. Had a long gap before dc2 and then fell pregnant age 43. I was healthy and fit, I had a contraceptive blip. it was a completely straightforward pregnancy and baby was healthy, I bounced back really fast and baby was ebf for 18months.
It was a really big decision to have a baby in my 40s but for me it was the right one. I contemplated how I’d cope with twins; how I’d cope with a disability; how I’d cope if my mum died (she did in fact die when my baby was young, and it’s hard to deal with a dying parent/bereavement and an infant).
I intend to stay fit healthy and young, godwilling, and prepare my kids for an adult life in which I may not be around forever.
I would think really hard about whether your lovely partner is cut out for fatherhood - how long have you known him? What’s his past like? who suggested having a baby and who is most keen?
if you have any doubts, just don’t do it - that’s my advice
With every year that passes your fertility drops. Sell yourselves the idea that a baby would be an unbelievable blessing but without , you can still be happy
