Today I accepted a new job that doesn't know I'm pregnant. I'm only 4w5d so I don't plan on telling them until at least after my first appointment on the 24th. The only thing is I have to go in on Monday for paperwork and the HR woman I talked to said something about me taking a flu shot... I've never in my life taken a flu shot and I never planned on it, especially not when pregnant and in my first few weeks. Will a flu shot cause harm to my barely developing baby? Not that I want to take a flu shot anyway.
