Tdap Question? Do I need a second vaccine ?

I received the tdap vaccination back in 2018 before I left on vacation for the summer. I am a first time mom and unsure if I will need to receive another shot since the tdap is good for 10 years. I see a lot of post regarding this and was just curious if another is recommended since I am pregnant. Of course I will speak with my doctor concerning the tdap. Please be kind :)
