Fetal movement question!

Anyone else feel like their fetal movements are off, not less but more movement actually. I’m 27 weeks and I feel movements consistently throughout the day like normal kicks and even hiccups randomly but at least a few times a day, I’ll feel these sporadic episodes that only last maybe 20 secs. I’m talking fast movements (like it reminds me of my toddlers throwing a tantrum, like flailing around and kicking) then all of a sudden they stop and movements will be more normal again.

Do I sound paranoid when I say I’m worried it could be seizures? I have no family history on my side but my mother in law has epilepsy. Are fetal seizures even a thing or will I sound dumb bringing this up to my doctor?
