I've only felt Braxton hicks twice (I think that's what they were, pain in lower uterus for a couple minutes, vaguely similar to period cramps). Is that normal? I'm 30 wks 3 days.
How often do you ladies get them? How often is normal? When do they usually come on more regularly? (Regularly as in daily or so I guess)
