Ring on a string💍

Mimi • Momma bear 🐻 expecting her second cub💙.
I've been trying to conceive for 4 months now and my best friend is pregnant with a girl. They noticed I've gained weight my feet have been swollen my boobs hurt and my face is changing like in color a bit. They held a ring on a string over my belly and at first it went back and forth then in circles and then bigger circles. My period is supposed to start tomorrow and I'm so nervous I hope I'm pregnant. My friends mom held it over her belly and she's not pregnant and it stood still so I'm so confused! Help me. Anyone else believe in old wives tales?
