We’ve just been through a similar situation.
After two DC in our 30’s, an ectopic pregnancy that nearly killed my wife and a resultant op to remove a Fallopian tube, we were very surprised to be pregnant again at 41. We don’t DTD very often either...
We talked about it a lot, both feeling like this might be one too far. But, ultimately, we couldn’t go through with an abortion. It was a personal decision, and I would have supported my wife if she’d decided otherwise.
As it happens, my wife miscarried last week, just as I was on my way to collect a cot (we’d sold all our baby stuff!).
We feel a bit lost, having reconciled ourselves to doing it all again, now life says it’s all change again.
I don’t know if this helps OP, it’s just my personal experience. Wishing you all the best with whatever you decide.
