transverse baby with unstable lie

Hollie • Married, young, SAH Mummy to a beautiful nearly two year old girl and expecting a little man the end of November!
I'm currently 33 weeks pregnant and my little boy is lying transverse with his head up in my ribcage, back down along the bottom of my stomach and bum in my right hip , though sometimes during the day he flips to being breech with bum right down in my pelvis. 
My midwife orgionally said he still has time to change position but as he's never been head down only breech or transverse I'm getting worried he's running out of room and won't turn in time. Has anyone experienced anything similar and had a good outcome?! Or any insite at all would be helpful thanks!
