Breech baby or just over thinking it

So i went to the doctor Tuesday and I’m 36 weeks and 1cm dilated. Doctor said baby is head down however he is still sitting pretty high. I’m terrified that he will flip and become Breech. The movement I was feeling around my ribs is now lower near my belly button...is this a sign he’s flipped the wrong way or that he just moved lower in the past two days. I’m panicking. I just want the baby to be healthy and in position. Really wanna avoid a c-section.
