20 weeks pregnant and all i drink is iced tea ?

Is this okay? We can't afford much and I dont buy soda, so besides the oj I'm always craving I always drink iced tea is that safe? Also, pretty much everyone I know who has a baby, he or she comes out looking like dad! Does it seem the same with people you know? I have tried to find statistics on which genes are more dominant, but can't really find any.
