Tying tubes by accident?

Tomorrow, I go in for my scheduled c-section and I'm absolutely afraid that they're going to tie my tubes without my permission! At my doctor's office, I've been alternating between the two doctors that practice there and although I've consistently told them I'm not having a tubal, I've still been asked at least 6 times during this pregnancy. THEN, the nurse just calls me to go over the procedures for my c-section on tomorrow and ask me how far I live from the clinic because they can't find my paperwork for my tubal and I'm like what tf... I literally JUST told the doctor on Monday that I am NOT having my effing tubes tied! Ughhhhhhh. I don't even know what the point of this post was because i can't exactly change doctors now but I'm just pissed that they keep bringing it up and super fearful that it may happen without my permission.
