I doubt you have much to worry about though, not with that type of exposure. Talk to your Dr. and as Ecologic said, they can
run bloodtests. I will tell you that I have two cats, and scooped and changed kitty litter whenever DH was away. I don't think I was ever even tested for it, and I did not have any problems. You should always be careful, but I doubt there is any problem. Good luck, and congrats on your pregnancy!!!!
