I would not only let them know you're pregnant, I would also request the salt or sugar scrub as me and my family go there all the time and now have our third child on the way and during those times she was concerned about the same issue. As an x martial arts teacher, and being half Korean myself and having been going to this place for years with my family I feel it has been safe and the health benefits our bonus :-) hope this helps!
Yes. You tell them you're pregnant before.
As far as I know. Just let them know you're pregnant and the massage part will take that into account.
