Braxton Hicks Contractions

Okay, so I'm 99% positive I'm an having these (I'm 32w 2d) but I'm curious how these feel to other mamas. My stomach just gets really really hard and then goes away after a bit. Is that what you other moms are experiencing? Someone told me they had to be accompanied by a cramp like feeling in my lower stomach, but I don't feel that at all. What are you experiencing?
