Seizure like movements?

Mariah

So I’m 26 weeks and baby boy is super active, non stop and very strong movements like punching/kicking and rolling but I’ve also had really strong “flutters” almost like he’s shaking violently and fast. Does this strong “flutter” feeling happen to anyone else and do u think it’s normal or seizure related?

I will bring this up at my next appt but wanted to see if anyone else felt this.
