Nausea & vomiting

Jess • Been with the love of my love for almost 5 years, married 17/08/19 baby, a boy 💙 👶 05/10/2019

I’ve been having nausea & what I call attempt to vomit off & on all day, during the night. My body tries to vomit but nothing comes up, it’s so annoying, has this happened to anyone else before? Any advice I would appreciate thanks
