Since 15 weeks every scan I've had my bub has been head down, so 15, 20, 28. I'm at 29 weeks now. He always feels the same so I'm assuming he's still in that position. Just like others have said, I can feel a bum or back to the right of my belly button and kicks above my belly button, under my ribs, little punches and flutterings near my cervix. Fingers crossed he stays that way.
Went to my first antenatal class yesterday and the midwife advised us to (from 34 weeks) lean forward and not recline too much where possible to encourage the bub to swing into the right position, back out, head down.
