TDAP vaccination while pregnant

So today at my doctors appointment, my doctor started talking to me about getting the TDAP vaccination. I’m all for vaccinations but honestly don’t want this vaccine while I’m pregnant even though it’s suppose to help baby be immune to whooping cough before being born. But honestly I don’t plan on leaving my house with baby for the first two month anyways unless to go to doctors appointments where she will get her needed vaccinations. Also, My niece had a bad reaction to TDAP & my cousin got the vaccination and still got whooping cough so I don’t know if it’s worth getting while pregnant. What do you ladies think?
