Hello. I am 22 weeks pregnant and all through this pregnancy I seem to have become periodically paranoia about toxiplasmosis. In the first trimester I ate some undercooked meat and got really upset reading about the terrrible effects of toxi. I had a test then that came back negative. Now I am worried again because I went on a camping holiday abroad last week, which involved unavoidably eating food with sand in it (it was very windy so sand got everywhere!) I know that toxi can be in soil and sand. I'm considering asking for another test. Am I being unnecessarily worried?
