Severe OCD while pregnant , toxoplasmosis

So I have developed really bad OCD while pregnant . I’m constantly washing my hands and changing the bed sheets etc . My husband takes care of the cat litter down in the basement . We have an outdoor cat. I noticed he changed the liter and I can’t help but to think he touched everything washing machine buttons , door knobs etc . Now I’m terrified to go down there . “What if I touch the door knob he touched kitty poo with ?” Can someone please ease my mind. I’m so over feeling this way. I do see a therapist once every two weeks or so. But can someone inform me about toxoplasmosis in cats ? I’m at the point that I want to get rid of him that’s how bad it is. Please serious comments only.
