Soda / pregnancy

I'm almost 3 months pregnant,in the beginning I didn't even noticed I was no special cravings nausea or anything .. after around a month (when I found out) I had this one day crazy craving of eating my fiancé's ranch dressing that came w his wings and I ate it all by itself 😂

With all that all I'm trying to say is I've been having lots and lots of cravings lately and even more food aversions .. including water .. I drink it a lot of course but sometimes the 'taste' of it makes me gag and I've been crazy for coke .. I've tried other sodas and they just don't seem to work as good as coke does .. is it risky? Any other soda or drinks options to help my sickness go away?!

Thank you all so much 💜
