Sorry, I'm sick so I was trying to cut corners haha.
If your cat has it, you're going to get it regardless of whether or not your clean the litter if you interact with your cat. It's why my optometrist wanted me to stop sleeping with my cat/ get rid of her since I only have one strong eye. Considering it has been years since your cat has been outside, if (s)he ever had it you would have it by now and it poses no risk to your current pregnancy because it has already been in your body.
The likelihood of a well maintained cat getting toxoplasmosis, even if it is an indoor outdoor cat, is not as common as people make it out to be. In my area now, where there is a high population of feral cats and pet cats who do not receive adequate vet care, I would be concerned about it. In a neighborhood that is well maintained, you're much less likely to encounter this bacteria.
I hope that made sense. I'm tired. haha Basically if you were going to get it, you would have already gotten it and your body has already dealt with it. Or you haven't gotten it because your cat doesn't have it so you won't get it now.
Either way, you're totally safe. I still recommend using gloves and a mask because of the dust, other bacteria, and ammonia. But when I first got pregnant, I would have been a single mom and I cleaned the litter every day with a cat like yours. Made it to 10 weeks without any issues, just made sure to wear a mask and wash hands after. Lost that bean for totally non litter related issues
I would get other people to clean my litter boxes if that was an option, but only because I am terribly lazy and hate doing it haahahaha
