Massage during 2nd trimester

Brittany

Okay ladies, first time momma and pregnancy experiences so help me out.

So I went and got a massage today. I’m currently 19 weeks along. I laid on my back for a fair amount of time along with my side. Could lying flat on my back cause any harm to the baby. I’m reading myths and things that say it can cut of blood supply to the baby, etc. while others say no I’m fine. Help ease my first time pregnancy mind :) thanks everyone!!!
