wow yes i see what you mean
when you say contractions do you mean period like pains arround your uterus get almost painfull enough for a paracetamol? need to lie down or rest to get them to go away?
i've had that a few times not not like contractions more like almost continuous pain the dr said it was most likely the ligaments and abdominal muscles stretching to make room for my uterus you should however go to your doc if you get a pain that doesnt go away after lying on your left hand side for a while
hope that helps
