TDAP Vaccine

Mi

Hello everyone! I have a question about the TDAP Vaccine. When I had my son 2 years ago, my doctor never offered me the vaccination, nor did I realize that it was an important vaccination. I'm current 28 weeks pregnant now, and tomorrow I am scheduled for the shot. I am wondering if any other mommas out there got their TDAP vaccination while pregnant? If you did, why? And if you didn't why? I have done my research on it, but am curious as to hear some real life reviews so to speak. TIA!
