Hi OP, first up so sorry you're finding things tough right now. My heart goes out to you - it's horrible when someone makes a 'joke' that stabs you in the heart :(
Seems to me that there's 2 issues here which you're letting get all mixed up in your head:
- first that you're very keen to be a mum and worried about being single and your age;
- second that you had a termination and the infection after.
I had a termination in my mid-20s and also had issues afterwards - bled for about 6 months, not ideal! They never got to the bottom of what was up and it eventually resolved.
Wasn't sure about kids but then DH and I decided to try at 36 and fell pregnant first time of trying. After DS was born my thyroid went mad and we were advised against TTC for 3 years! Got the green light to try again in March and by end of April I was knocked up - due in Jan, when I'll be 40 and a half years old! All looking super healthy, fingers crossed...
But actually last night I had a nasty hormonal pregnancy dream where the doctor told me that because of my termination I'd have to terminate this one too :( There's such a lot of trauma and guilt about terminations, it's all still so taboo even though so common.
I think one really productive thing you could do might be to find a cousellor (if you can) to try to get some closure on the feelings you have around the termination? And you could also look into the egg freezing thing if you have funds, but as I said for me at 40 the eggs seem to be fine...
Lastly I'd just say, as I know PPs have said too, that amongst my friends it's gone all the ways - some folks unplanned pregnancies working out fine, some folks with all kinds of fertility challenges, some child-free by choice and loving it, some childless when they'd have loved kids but finding the upsides - which tend to be more cash and time to spend on yourself and your passions in your 40s and 50s!!
I wish you all the very best of luck whatever life gives you
