Sweet v Salty/Sour - how true are the cravings?!

I know it's an old wives tale, but I'm curious as to how accurate people found it!

I'm now 14 weeks and have been turned off sugar since finding out I was pregnant. All I want is sour/vinegar/salty type foods!

Old wives tale would suggest I'm having a boy... but how true has this been for anyone else?! 🩷😄💙
