Td only or Tdap?

Patient: I’m 9 weeks pregnant and my nurse asked me on my first visit if I had a tetanus shot and I told her yes, she asked if I had it in combination with another vaccination and I couldn’t remember. I looked at my records and I got Td in 2010 but not Tdap, do I need to get the Tdap and not just the Td? Is it still good to get the shot in my second trimester?Thanks a lot!
