starlightmagic and Bubblegum89 - It’s heartbreaking reading about how you both feel your issues with conceiving might be karma from previous terminations, though I know you’ve said you realize it’s just rotten luck, Bubblegum. Believe me, I understand how confusing your feelings can be about that decision, even years later. I’ve been there.
I don’t know if this helps at all, but be assured the NHS says that abortion has NO EFFECT on future fertility (except in certain rare cases or in the case of multiple terminations, and even then, you would have had symptoms at the time and there would be clear signs now).
None of this is meant to simplify your feelings at all, which I’m sure are still very complex. Personally, I don’t believe pregnancies are connected that way, exactly - for example, that a future pregnancy will not happen because that pregnancy already happened in the past (and was terminated). I think each pregnancy has its own time.
I hope you both get your BFPs and know that, as hard as it must have been, it sounds like you both made the absolute best choices in the past you possibly could, to make the best future possible. That’s what good mums do, so you’re already one step ahead.
