No you're fine. The only reason I found that I couldn't drink soda was because the carbonation gave my daughter bad gas

Too much caffeine is not good for your baby, but in moderation you're fine.

no I was told you can eat or drink what ever foods you want your not restricted like when were pregnant that's my 1 one weakness I love that soda and could drink it all day but I got myself hooked on water and Gatorade at the moment
