Worried baby will turn breech 38+5

Baby boy was breech at 34-36 weeks turned head down at 37 weeks confirmed by US at my last appointment baby was still head down. I'm worried because he has a ton of room to move around and since he has yet to drop my dr said there is still a chance of him flipping around again. Today I thought I felt the head by my rib cage and even felt jabs to my bladder, then tonight I felt hiccups in lower pelvis area which would suggest head down. I feel very stressed out not knowing for sure where he is. My dr has said that if at my upcoming appointments he's breech they would have to schedule a c-section as well as at the time of labor if he's breech. I'm absolutely terrified of having to have a c-section. 😰
