I'm 33 weeks now, what is the best thing for me to be doing for myself and or the baby?

exercising and eating right. diet soda if you can't stop drinking soda completely. and limit your caffeine intake

I've been trying to do that but one of my cravings is soda! I didn't even drink soda before my pregnancy! lol

And eating healthy(ish)

Resting as much as you can lol
