TDAP hasn't happened yet?!

So, I'm SUPER PRO VACCINE. I hit 36 weeks yesterday and realized my doctor hasn't offered me the TDAP yet (already got my flu shot though, since he suggested it back in October). I called and asked them what the deal was, and they said I would just get it at the hospital when I deliver. The CDC recommendations are for me to get it during third trimester. 😕 Has anyone else run into this problem? I'm guessing I'll just call my general practitioner and ask him to prescribe the shot?
