shaking uterus ???!?!

Cecilia

help me !!!! I was sitting in my dinning room and all of a sudden I felt my uterus shake a little bit. like a tiny earthquake! i took a pregnancy test a week after suspecting I was pregant and it was negative. and I got my period right away. I just finished my period. could it be that I'm pregnant or is there something wrong with me ?!??!
