Yes there are exercises you can do, but do check with your Gynae to see if you can do them, after all each of us has diff body conditions. Something I found online and people say it’s effective: https://youtu.be/s-szODdpg8A
There may/may not be a chance that baby will turn head down. It all depends on baby and if let say baby dont turn head down soon, dr/gynae may suggest for ECV procedure.
You can start talking to your baby to ask her to turn head down too ☺️ it might help.
