Went for my 34 week Appt and contracting??

Nic

So I went in for my Appt and they hooked me up to the NST ( did it at my last Appt too. ) dr came in and saw that I was contracting and was surprised that I couldn’t feel any of them!!! He didn’t seem to worried and said to come back in a week to check again and if I start to feel pain or anything to head to L&D. First time mama here but are those strong contractions that I’m not feeling?
