18 weeks with my first, 16 with my second, and they kinda felt like nothing, more uncomfortable than painful. Felt like my belly was being squeezed but not in a painful way. the further along in pregnancy the harder they got.

it felt like death. lol naw it was more of a pain mine were more up at the top of my tummy and below. you know there braxton hicks when you can still bare them and talk through it. i got mine later in my pregnancy though like. last week. and im 34 weeks now.
