funny belly question

So I read all these books etc saying my baby at 22 weeks now should be right at my belly button. I have come to realize this must only be for women who never were 400lbs and lost 250lbs because when I look down at my belly or in the mirror for that matter the baby appears way further up. I do realize this is all from my lovely sexy sagging skin, but I find it funny. Anyone else have these issues

I'm 22 weeks also and mine is the exact opposite.  I started at 480 and have lost 240 lbs and this baby is still really low.  I have tons of sagging skin and you can not even tell that I am pregnant.  I think the skin does a really good job of hiding the baby.  I am hoping as I get further and baby starts getting bigger, it will actually look like I am pregnant.  I do find it funny.  When I was pregnant with my first, 12 years ago, I was about 330 lbs and you could so tell I was pregnant at this time.  It's funny how different each pregnancy is.

My baby is higher than my belly button!  Uteruses are like other body parts, there is an average size and location....but it does vary.  My dr has commented that my uterus seems to be higher than average.
