Get baby to turn.

Ok so i really have no idea on what position baby is in at the moment and my OB really gave no indication either!

Most of the kicks and movements i feel are really low still and i get the odd hard lump under my breast, (feels a bit like a head i think)

So i want to know if there is anything i can do to help get the baby in a head down position and hope that he stays that way. lol

Ive not been working this whole pg so spend lots of time lying on the couch ect, maybe walking more would help? Ive also heard about getting on all fours (for labour?, but could this help turn?)

Any tips would be great

Thanks
