Baby movements?

žœ • expecting our rainbow baby april 2nd '15 ?
So I'm nearing 14 weeks, I know that's early.. Butttt, my uterus is about 3 inches bellow my bellow button, and for the past few minutes I've felt some weird things. It's not like an air bubble, those are uncomfortable. This is indescribable.. It could just be other things moving, and if anyone else seems to know what I mean id love some answers.. 
​It's almost making me nauseous. It's slight and subtle. But if I stand super still in my low stomach it's like something is moving back and forth.
