I'm 22 weeks pregnant and have 2 cats, who are 7 years old and very keen hunters (despite having two bells on their collars!) 
They don't have litter trays and go to the toilet outside. I am also vegetarian so never eat meat, let alone undercooked meat. Because of this, I never really thought much about toxoplasmosis and the only precaution I've taken is to be extra careful washing fruit and veg and when gardening.
My long-haired cat was sitting on my lap last night and I noticed that she didn't smell very nice... it turned out that her bum was a bit dirty 
I suddenly feel very paranoid about the fact that the cats sleep on our bed. They also have access to the kitchen, and I've realised that I may not always know when they've been on the work surfaces. I do keep the kitchen clean, but I don't freshly disinfect the surfaces before preparing food every time. It is therefore possible that the cats have been on the work surface at some point without me seeing them, and I've then prepared food where their (potentially contaminated) paws have been.
All of these thoughts are firstly grossing me out a bit, and secondly making me rather worried. Am I over thinking it, or should I ask to be tested for toxoplasmosis? I've done a lot of reading and it seems that cat owners often haven't actually picked it up before - only 30% of adults have had it and most of those come from food rather than cats.
My main reservation to getting tested would be to find out I've been infected in the past, but not currently. Because I'm well into the second trimester, it may now be difficult to assess whether I was exposed long before pregnancy or at the beginning of it. I can see it opening up a can of worms and leading to a lot of stress, which may be unnecessary.
Does anyone know more about this and could very kindly share their thoughts?
