34 weeks and no Braxton Hicks?

Mikayla • I'm 23, married for 4 years, we have a beautiful 2year old little girl! she is our universe!!!! I'm a cancer in a home with two Capricorns!!!! Baby #2 due may 2019!
So I'll be 34 weeks tomorrow and still haven't had any Braxton Hicks and I'm having a perfect pregnancy so far but they keep asking if I've had any and when I say no they get an odd look on their face.... Is this normal? Or should I have had some by now??
