Keep craving for sweet things and coke (Pregnancy)

I have hard time controlling myself for sugary foods this pregnancy. Previous pregnancy was okay. Didn't have much craving for sweets or coke. Had craving for bubble tea more. This pregnancy has no craving for bubble tea. But have craving for sweets, coke and ice cream more. I feel like I'm harming the baby inside me. But it's just so difficult to control. I don't drink coke often. Just a few mouthful once per month. It's so difficult to push myself away from coke. What's worse is, I don't like coke before being pregnant. 🤦🏻‍♀️
