Get you get pregnant week before tubal removal?

I may sound slow I apologize lol. I forgot to ask my ob at my pre ob appointment but I get surgery next Friday to have my tubes removed. I was told to take my birth control out the week before which that makes this Friday. I’m on the ring so I’m suppose to put it in today but I’m just not going to put it in since I would have to take it out in a couple days anyways. Can anything happen if we have unprotected sex within this week before my surgery? Even though my tubes be out I know you can carry a child but like does sex within that week cause anything? I really forgot to ask at my appointment.
