coffee and soda over protective boyfriend

Hey everybody... I usually have a cup of coffee every morning b4 work but since I found out I was pregnant my child fathers will take it from me.. he doesn't let me drink soda either and for some reason Pepsi is the only thing that helps me with being sick.. so I'm coming to y'all can I drink coffee and soda. Is it harmful for the baby or just not good to have... if it's harmful I'll stop of course... I just need to know wat to tell him bc I don't know lol
