Hello everyone! I'm going for an ultrasound tomorrow and getting blood tests for genetic markers on Tuesday. That being said, everywhere I look it says you can't eat fatty, spicy food or alcohol the day before, but there's nothing about sweets! I've been dreaming of halva for two weeks now, and today my husband bought it as if by chance, I really want it! And honestly, I can't live without sweet things lately! What do you think? Can I or can't I?
