Freak out moments

Anyone feel like they're going crazy?  I'm 24 weeks. 
Today I had a facial to help with some of the pregnancy acne. I was lying on my back for about 45 minutes during the facial. The babe was kicking and moving tons, and she still is. 
So why do I feel like I somehow did some harm by being on my back??  
Anyone else freak out over the dumbest things?!
