Solar Eclipse beliefs

Ruby

So I'm Mexican American. Both of my grandmother's are very religious (jw) so they're not superstitious at all until it comes to an eclipse. I got phone calls from both of them, my mom, my aunt and my stepdad. They all told me to wear a safety pin with a red ribbon on my underwear close to my belly. I'm going to just to be safe than sorry. My fiance thinks I'm crazy, he's not Mexican lol. Anyone else doing this?
