Feeling baby move super low

Kelly • Pregnant with my second child, due February 21st! Were very excited to be giving our daughter a sibling!
I'm 21w2d with my second daughter. When I feel her move and kick she feels soo low that I told my fiancé I feel like a foot or limb is gonna come out of my vagina! I know that doesn't happen but just for a general idea of how low she feels, lol is this normal? With my first I feel as if she sat much higher!
