I really don't think so. I crave candy sometimes also. I'd say go for a couple pieces !, just don't over due it.
I eat a few chocolate bars a week.
It won't hurt baby.
Everything in moderation. As long as you're eating healthy foods as well and not just sweets 24/7 you're probably fine.
Chocolate in moderation lowers your risk of preeclampsia and studies have shown that eating chocolate makes a happier baby:)
