Prenatal massage-should I be annoyed?

Jen
So I had a prenatal massage today. Spent the money at 38 weeks mainly hoping it would relieve the knots in my shoulders which I swear are so big and tense they could grow minds of their own. 
I assumed that being prenatal the masseuse would go light etc. so I told her more pressure. At least twice cause I'm not exaggerating when I say every handshake I've ever had was more pressure than this massage. 
Is there a rule or something about pressure and prenatal massages ? Should I be this irritated?
