I don't know how to approach this with my providers

It makes me uncomfortable when my midwives ask about birth control after birth. I go to an office where I see a different midwife every visit and they always offer tubal ligation (this will be my 3rd baby and scheduled c-section)  and when I tell them I am not yet done having children they still push other methods of birth control like the pill. I personally don't like hormones messing with my cycle and I don't want or need birth control. My husband thinks I should tell them to make a note in my file to stop asking me about it.  I am worried about what they will say, but I have been sexually active for 13 years and know how to ask for birth control if I want it. Is it rude? Should I just keep having these awkward conversations? I mean is it rude of me to tell them to put it in the file to never ask me again
