I am 10weeks pregnant plus 1 day. Before I knew I was pregnant I was taking hyaluronic acid oral supplements. Could this have hurt my baby? I am also concerned about herbicides and pesticide usage in my area. On 2 separate occassions they were used in my area and the smell got into the house. I closed all the windows and doors as soon as I detected it but I'm also concerned about that exposure too because I have heard that pregnant women are supposed to stay away from those things. Should I be concerned?
