mines like that. i figured its because that's where my LO's feet are and it's how i'm able to tell he still isn't head down *sigh*...but my top of my bump sticks out wayyy more so it's probably not the case for you x
No hun, if you have some pudge down there baby can't get out of your uterus and into the pudge. I have my nasty little fat bit down there and baby is for sure head down. She was footling breech till 31 weeks and when she turned there was hardly a difference in bump shape.
Does your midwife ever mention if baby has changed position or not? For me it was easy, I felt her flip while I was flying to my families down south, and I happened to be booked for a 3d while I was down there.
