I agree that massages are great and I believe a necessity in everybody and more importantly pregnant women. As a massage therapist myself I would recommend that you find a qualified massage therapist who knows how to massage pregnant women.
I wish i could afford one every week, but monthly will have to do.
Also make sure you know what oils that they use and be familiar with them yourself. I was 19 weeks and went to have a pedicure. I told her that I was pregnant and she still put peppermint on my feet!! I was so angry.

Goodluck to everybody for a great pregnancy.
