Too much movement!

So, I'm a first time momma and I'm 22 weeks today. 
I've been feeling baby kick and move since around 17/18 weeks and it's amazing and I love feeling it. 
But as of this week, she seems to just wriggle and move ALL THE TIME! 
My question is, is this a bad thing?? I don't want her to get all like tangled up or rupture the placenta or anything! 
I know that's super dramatic and I'm probably being ridiculous, but it feels like she's going to burst through my stomach like in the movie Alien! 
Does anyone else's baby move like crazy without any sort of "propositioning"? (Like no cold drinks or sugary stuff etc). 
Please don't call me stupid or anything like that because I already feel silly for asking!
