Movements are hurting??

Hi ladies, I'm 34+2weeks and my belly is ALL baby!!! I feel every single movement that she makes, but recently, I've found that she sticks something small and knobbly out and as she moves it along the inside of my stomach, it actually really really hurts? She's head down and it's normally over the sides of my stomach making me think it's probably an elbow, foot, or knee.. But I don't know if it's normal for it to hurt when she sticks it out and moves???
