ok so i have been doing the nub theory for over 6 years and always assumed that
if you get a good nub shot once it is visible at 9 weeks plus you can venture a
good guess about gender. now i have had a scan at 10.4 weeks and read in some
other posts that scans less than 11 weeks and a few days are not
accurate....
now if the nubs of both boy and girl is a protruding tubercule
at the end of the bottom and one determines gender by the angle of the dangle
rule....then why is a nub that is clearly visible at 10 weeks not anymore
accurate than that at 12 weeks? has this something to do with the fact that the
tubercule is flexible at that stage i.e. 11 weeks or less and can move from one
angle to another and as the weeks progress i.e. form 10 weeks to 11.5
weeks.....the tubercule becomes more rigid and fixed into place based on the
gender of that baby?...cause that will only explain to me why a nub seen at 10
weeks in whatever position is less accurate as the same nub at 12 weeks. cause
in both stages the tubercule is still protruding.....and sticking out the
same.....
can someone clarify this for me please as on pic shows my nub
pretty flat and it was like that most of the time during the scan and i have
seen that too at 8wand 5 days (i had a clear white line at the end of the bottom
but was told it was too early then) and then i have another pic of the same scan
and it looks like a 90 degree nub......sticking up......although i concentrated
and i knew that at times the leg got in the way but if you see my boy nub pic it
really looks like a perfect boy shot.
i have another third pic and the
nub cannot really be seen but i see something of fork hiding behind the
thigh....
i would be really curious as to why 11 weeks + is more accurate
than less than 11 weeks....when at both times the nub is sticking out just the
same....
so the question is....are nubs less than 11weeks flexible and
those at 11week+
