Polyhydramnios

Looking for other mamas who have been told they have Polyhydramnios. I’m so scared for the well-being of baby given what I’ve read online. For months baby has been in head down position & suddenly flipped around (breech) @ 35 weeks. I’m 37w 2d today, baby last week on 12/6 was 8lb 1oz still breech - I’m no longer going to be monitored by the high risk doctor. Today during routine OBGYN visit baby has now flipped & is head down again. Can anyone share their experience with Polyhydramnios - good or bad. Did you have a C-section or vaginal delivery? Any complications with yourself or baby? Due to baby being breech my scheduled c-section is 12/28 but now I’m given the option to do either C-section or vaginal. High risk doctor does not want me going to my due date of 1/4 due to history of preeclampsia.
