Too much movement?

This is going to sound super silly but has anyone experienced too much movement leading to complications or perhaps a problem?

Im 18+5 and i have been feeling movement for a few weeks now but it has been few and far in between.

However today baby has been moving like crazy! In the last 4 hours, I’ve been feeling kicks every 5-10m at least. As much as i love it, so much movement all of a sudden makes me worry that it could be due to distress or some crazy complications like baby having seizures.

I know im probably overreacting and this is my 3rd child so you’d think I’d be more relaxed about everything but i cant help but worry!

And i know movement right now can be all over the place but has anyone experienced THIS much movement this early? Like i said, its almost nonstop for the last 4 hours
