My bub turned frank breech at around 30 weeks. My OB made me get on my hands and knees for 15 mins 5x a day until she turned. I knew she had gone breech as I couldn't hold any food down and was so sick from the pressure on my stomach. I had 4 weeks to turn her back otherwise my OB wanted to book me I'm for a csection (probably would have changed to an OB who'd support a breech birth). The day after my appointment the pressure and nausea disappeared and she's turned by herself. I was lucky!
