Symptoms.. Are any myths true?

Mekia • 2baby boys 🧡
I'm a FTM! Tomorrow I will be 18 weeks pregnant. I don't find out the sex of my baby until January 4th. I've had no sickness, if I'm craving it's sour & spicy, my nose is spreading but nothing else really.. When they say "a toddler boy strays away, you're having a boy" "toddler girl strays away, you're having a girl" ... Any suggestions mamas???
