TDAP vaccine side effects?

I’ll be 28wks tomorrow and had the TDAP vaccine as well as my glucose test yesterday. I was fine all day but I’ve been up since 3am with diarrhea. I never have had a reaction to this or any other vaccine before but wondering if that’s what it is. Did anyone else have this kind of reaction to the TDAP?

Edit: and now I’m throwing up. 😳
