Rapid movements?

I previously made a post about being worried about hardly any movements. Well now I have the opposite concern. Ever since I laid down last night I've been feeling fairly rapid movements. Sort of like how a fish would move out of water. And also it feels like she's putting Her foot in my cervix. It's a repeated slight pain there. And there's a lot of movement. Is this normal? Again I'm sorry if these are all dumb questions or concerns, I'm a new mom.
