Any Massage therapist out there?

I'm currently 17 weeks pregnant and a massage therapist in a chiropractors office. I'm doing 4-8 massages in a day and I feel ok with that for now because I'm not too big. How long were you able to work with proper body mechanics? I'm nervous that I'll be put on leave early because of the kind of work I do. Very deep tissue, very straining. Any mama's out there ever been in this position? What did you do??
