Breeched baby

I’m currently 36 weeks when I was 31 weeks I had a ultrasound and the tech said the baby was breech and that she should turn but she still is breech I can feel her head when I push on my tummy I have doctors appointment on Tuesday and they are going to do another ultrasound to see if she is still breech but I know she is bc like I said I can feel her head but they said if she is then they will be scheduling me a C-section I never had one before this is my 3rd baby my other 2 was vagina delivery. I’m kinda scared to have a C-section.
