i had peritonitis in my 20s while travelling aborad . they told me then what you have been told about the risks etc. After i had surgery they told me that one of my tubes was bent so i was at more of risk of an ectopic pg.
when i eventually tried to conceive i got pg right away, then got an UTI at 6 weeks and miscarried, which apparently is pretty common if you get an infection this early on
i then got pg immediately again, they gave me a scan at 6 weeks ( in case of an ectopic, nothing to do with mc). everything was fine and i had a healthy baby at term
9 montsh later got pg again immedialty, despite BF. again had scan at 6 weeks to check not an ectopic. again had another healthy baby at term
so despite pretty serious infection and dire warnings AND being very old, i had no problems whatsoever in conceiving or in miscarrying ( as it was simply due to the infection). This could easily be your situation too. yes, the risks are higher, but many women are fine.
i would guess that your GP will just tell you to just go for it it you want another baby! If you have been TTc for a while with no success they will do some investigations sooner rather than later. they won't want to do a laparoscopy now ( to check your tubes are patent)as any surgery is just more of a risk IYSMIM
if/when you do conceive they will probably scan you early, which is in fact very reassuring, coz you get to see your baby's heartbeat and knwo he/she is fine
