Vibrations/sensation lower tummy area..normal? Early in preg

Hello after dinner, I got up quickly and felt a pulse-like sensation on my right side of my tummy. It lasted for about 10 seconds, then another one quickly after. This was not cramps but something completely different that I have never felt before.
I am only 6 weeks, 3 days and a new pregannt person. Please help. Is this normal?
I am resting now hoping everything is ok
