Aiii don't worry lah, my first one also like that until almost 36 weeks, then tiba-tiba pusing kepala bawah! Babies sometimes take their sweet time to turn, and 34+ weeks still got time lagi for baby to get into the right position. A few of us in my mum group had the same worry, and most babies sorted themselves out by 37-38 weeks, so I think yours will be fine too, but honestly best to mention to your gynae at your next checkup just so they can monitor and give you proper peace of mind, okay?
