I got my flu shot at 9w! After hearing the news about pregnant women getting the flu & autism, I didn't hesitate (I put a link below for you to read). In fact, it's healthy for your baby! If you get the shot while pregnant, the baby is vaccinated for 6 months after birth. If you are still nervous, talk to your doctor. Congrats & Merry Christmas!
