There is no scientific evidence behind that wife's tale... it simply is not true more than 50% of the time. It has more to do with the position of your uterus and your body, being that this is your first baby or even if you are younger- your muscles are tighter and more resistant to stretching. @ 24 weeks the very top of your uterus is probably just varily over your bellybutton. The uterus reaches the bellybutton around 20 weeks, so you are not likely much past that, therefore she could not possible be all the way up there.
I'm pregnant with my 2 nd girl and my 1 st was high and this one has been really low. So i think it just depends on where the baby finds a comfy spot.
I'm carrying high STILL at 37wks! I'm having a boy!
I carried low an had a girl.
I did. Where you carry means nothing, it is just where the baby is.
