How does the 6week pp check up go ?

Just had my 6 week pp check up and the dr was going to insert that thing that expands inside of the vagina to check it, but I’ve never gotten that before when I had my 2 other kids. The dr was kinda rude about it too, when I asked why she was going to insert that she said “I thought you wanted a checkup I don’t know if you ripped inside so I’m checking” I said “well I didn’t rip inside only on the outside” she looked at me annoyed and said “okay”. I miss my old dr sadly she retired but she was way nicer than this one.
