Dr. said I should get the Flu shot and Tdap

I have never had the flu in my life and neither the flu shot. I’m scared of getting the flu shot and getting sick lol... and also I don’t remember getting the Tdap shot on my first two pregnancy ... I’m just not comfortable getting all the shots while I’m pregnant since the baby will get the same shots later, I feel like its over doing it or something ... am I wrong?
