Is that our little one?

If I have a unicorn uterus and am missing the left side of my uterus, why do the movements that I think are the baby on that side? The movements are about an inch above my pubic hair line and a about 2 inches off center (on the non uterus side).  Any suggestion?s  Is it not my baby?  It doesn't feel like round ligament pain at all but king of little jabs, they are a little painful and stop me in my tracks.  Some of them feel quite low like they are in my cervix.  I don't have gas and actually went to the bathroom today so I don't think it's that either.  It's only 12pm and I've already had two full trays of ice and there is a lot of movement.  After some research I found out that ice water wakes up the little one.  Go figure.  You think I would have put two and two together but pregnancy brain has kicked in full force. 

What do you think?  Could my half uterus be off center by that much?  Is it not the baby?
