I made a mistake, I am seven weeks pregnant and at 5 weeks I laid a tile floor with thinset concrete. I did not use gloves or mask. Then just yesterday I started to grout and then realized that it had a warning for birth defects and immediately stopped. I probably worked for an hour with it with not protection. What do you think the chances are that I hurt the baby. I am very concerned. I feel sick that I did this and couldn't sleep last night I am so worried, what should I do?
