hi, I am seven weeks pregnant. I broke a mercurial thermometer this morning when testing my basic body temp. The broken mercurial thermometer was in my mouth. Unfortunately, I had a small dental ulcer. I do not think I swallow any of them, as I washed my mouth with about 1 litre of water and had a liter of milk afterwards. I cleaned the spilled mercury by my bare hands, although I was very careful not to touch them. I did not ware masks during the time I made the cleaning, and the window was closed. I am worrying if this gonna do any bad to my baby. Thanks Doctor!
