My LO was a breech baby. although we didnt know this until I was 10 days overdue and 3cm dilated!!!. I ended up having an emergency section. Cant really say it was a bad experience, or if anything was any different as we had no clue. Three midwifes examined me that day and didnt know she was breech until I had an internal.
only slight complication we have had is my LO has a dislocated hip, this is quite common for breech babies.
At least you know and they are monitoring you, and you wont go overdue if baby stays breech they will get you booked in for a c section.
