What does it mean ....

Angel • Mother To A Beautiful Baby Girl ❣️👩‍👧 .
I'm 7 months & I started getting this feeling as if the baby is in my vagina , like it feels like little kicks down there but I'm not sure that's what it is , & one time it felt like so strong , I thought I was about to pee on myself or something . 
Does anyone know or can tell me what that means when you get that feeling ? 
Oh & sometimes it's like it hurts but not really.
