Pregnancy superstitions?

What kind of crazy advice/ wives tales/ superstitions have you been told? My mom told me not to raise my arms above my head bc it'll make the cord wrap around the baby neck, my Spanish co-worker told me not to go barefoot or sweep my house for 40 days after baby is here bc I'll get fat if I do lol. One of my Laotian patients told me my baby will have good luck bc I have tiny lips.
