Hi,
As long as your massage therapist is familiar with pre-natal massage and the proper way to position a pregnant women on the massage table... you are able to receive massage right up until delivery.
I personally have what our industry calls a "Prego Pillow". That allows me to give a face down massage to the pregnant women.
Special pre-natal massage training is a must, so inquire before you book you appointment
good luck!
