Im not sure, dont have an answer for you. I seem to be lost on what is going on with my body even though i had a baby 14 years ago. Some days my belly is hard and some days it is very soft as if nothing is in there. I am noticing the baby is positioning herself in my side, almost like in my back, i will be asking my OB about it next friday.
I had this all day yesterday and I thought they were contractions...I don't see to have the same feeling today for some reason. I'm guessing it could be both capacity and contractions...not sure...
