Vaccination question - Tdap

Do pregnant woman get the Tdap vaccine during third trimester even if they have had it before in their lifetime? I think I had it as a child and then 10 years later got the booster. So I’m a bit confused and just trying to gather info before talking to my Dr. He basically just said “you’re 33 weeks so you should get it ASAP.” The CDC website just says “a pregnant woman should get the Tdap vaccine every pregnancy” but doesn’t address if that’s applicable even if we’ve had it before.
