I just found out i was pregnant today… well a week or so ago i was at the dentist with my daughter and she needed an x ray on her teeth. she is only 2 1/2 so i had to hold her on my lap while they did it. now i remeber them asking me if i was pregnant and i answered no because at the time i had not idea… what are the risks??? if any since she was on my lap and she had one of those vests over her??
