I'm 20 weeks, and sometimes when I'm lying still and can feel the baby moving lots, I notice that my stomach goes really hard - sometimes just on one side - do you think this could be the baby turning? Anyone else had this too? I did think it was braxton hicks, but it's happened quite a few times in the past hour and I don't think braxton hicks happen that often. Pretty sure it's nothing to be concerned about as it's completely painless - just a bit strange.
