Flu shot or not to flu shot?

Should I get a flu shot? I'm 5w5d and have never had a flu shot but I have also never had the flu. I have a job where I frequent doctors offices but mostly psych not pcp's where most people with the flu may go. I am nervous to get one due to mixed reviews of them, but I also want to do what's best for the baby. Anyone in the same boat or have some advice?
