Slight cramps?

Elizabeth • Mommy of one beautiful girl, and twin boys (:
16 weeks 3 days, and I'll have cramping, I think are braxton hicks. My whole stomach gets hard, then it goes away. I'm not use to having braxton hicks contractions, I only had a total of two when I was pregnant with my daughter. So I don't really remember what they felt like. Does that sound like them?
