RING TEST

I'm only 8 weeks along so I can by no means back anything up. BUT when I hung my wedding ring on a cotton string, put it about 1.5 inches away from my belly, i kid you not it felt like a gravitational pull and started going around in a circle, fairly strong. I take it away from my belly- back and forth. Put it back, round in a circle. Every website i go to says something different.. so at this point i dont even know lol. Which do you go by and has it ever been accurate?😅
