I have the urge to vomit

Ch

I have been having the urge to vomit randomly. I won’t have any stomach pain or anything it will just come out of nowhere. I also feel almost full all the time and really bad acid reflux. Would this still be considered morning sickness? It feels better if I can let out a big burp but I can’t do that at work plus I’m scared I’ll do it one time and actually puke everywhere. It’s like that saying never trust a fart. Well I don’t think I should trust these burps either.
