Is it safe to change kitty litter when TTC??

My husbands step sister had a miscarriage after cleaning up cat poop of her door step while pregnant. (She also poured bleach on it thinking it would help “kill” the germs that were dangerous to a preggo 🤷🏼‍♀️) Anyway, I’m terrified to change the litter during my TWW and was wondering if I’m being irrational or if I should leave that to hubby??
