Fet 3ab embryo


hi all I had my first Fet today. doc said it was a 3ab embryo , not sure if it's good or bad.. also I did not get to ask them do's and don'ts 😪😪.. I was way to sleepy from my accupunture.. please share your thoughts. when is it safe to have sex? and when can I start lifting my 6 year old, some times she wants me to carry her for fun
