Hi, I'm nearly four weeks pregnant (just found out) and today without thinking went for a manicure and pedicure at the nail salon. Anyway, when I got home I got really sick (dizzy, nauseaus, hot sweats). This went on for a couple of hours. Just wanted to know if at this early stage in my pregnancy this could cause birth defects in my baby since it got me so sick. Any help and advice would be greatly appreciated as i am very worried.
