Baby shaking in womb?

Kayce • Hello :) I'm a FTM expecting my daughter Lilah to arrive June 10th
Has anyone felt like a shaking movement from their baby? I can't tell if she is just moving fast or if something is wrong like she is having a seizure? It only lasts maybe 3 seconds at a time. Let me know if it's uncommon and I should see my doctor or if it's normal? I'm a FTM. Thank you.
