She shouldn't have done that... I was told not too in my first trimester.
My mom also told me its bad to get a massage in the first trimester.
The person giving you massage should certified to do so when you are expecting. There are points that shouldn't be massaged in pregnancy. I have read this several places and was told the same by my acupuncturists. I would think you would be ok but make sure your next one is done by someone certified.
I am not sure but when I had a massage done they asked how far along. When I asked why he said because they do not do people in the first trimester due to health risks.
