I'm absolutely pro-choice, and you should do what's best for your situation.
I would, however, echo, that friends who were only children, and are starting to lose parents, etc., are saying they wish there was a sibling to share the load - and to have a family remaining. However, if you've got a large extended family, that could probably fit the bill there.
I sadly couldn't have kids, despite lots of trying, but I do know that, when I was in my early 30s, I did have a pregnancy scare (laughable, as I later couldn't get knocked up, however hard I tried....) I was 100% on board with a termination in that case, as it was from a fling, and I was in no way ready for kids.
You are the only ones who can make the decision, no matter how much advice you take. Sending hugs; it's a tough one.
