Quoting Summerfrost:" The eggs don't die ..... the quality of the eggs is not as good as you get older, but the risks from ... [snip!] ... makes pregnancy possibly more complicated for OP. That's not saying that it will be, but there is a chance that it could be. "
i'm not 100% sure but i thought i'd read several times that eggs die quite rapidly... so just googled and found this but i must admit i don't know how credible it is but it is certainly interesting!
i get what you are saying though the more her reproductive system goes through and the more invasive it is might affect her fertility.
(the next bit is not aimed at you just general!)
i thought this happened to me- in fact last year i was 100% convinced that i had Asherman's syndrome.. as i had been unlucky enough to have my first ever IUD fitted and within a few days it perforated my uterus i needed emergency surgery to get it out... i had all the symptoms, very light but very painful periods. a perforation could have caused scar tissue, but i was wronger than anyone ever was wrong, for i have been pregnant THREE times this year!!! both my abortions were surgical... the first was at 11 weeks, and i was pregnant again just four months later AND we had used a condom.... so a big ol' hole in my uterus AND a vacuum/curette procedure didn't appear to make pregnancy difficult to achieve in my case... some people are just more fertile than others i admit i have made mistakes and 5 out of my 6 pregnancies were unplanned... BUT 3 of the accidents were NOT caused by carelessness, BC failed us; some people just get pregnant easily so i think maybe some people give OP a break? ;)
re- the scarring... i know a little about this from my Asherman's research i did last year- it can cause infertility and miscarriage mos def but i don't remember reading anything about birth defects... my understanding is that vast majority of birth defects are caused by chromosome abnormalities (complete chance, nothing you can do about it other than selective IVF) and the other few are caused by exposure to toxins during pregnancy x
