Should I be concerned ?

I just had something odd happen and my anxiety is getting the best of me. I got up because I had to to throw up and right after I finished the spot where baby always kicks I felt very odd movement it was like pulsating or spasmy movement that happened every second for about 5 seconds. I read about fetal seizures and I’m just so paranoid. I’m only 24 weeks but I feel baby very consistently and this was not a normal moment. It didn’t feel like hiccups because it was so quick and stopped after about 5 seconds
