15 wks 3 days ultrasound & a little peace of mind

Today I had an ultrasound at 15 weeks 3 days and I got to see the little peanut moving and flipping around in there! I've had 2 previous miscarriages at around 15-16 weeks and I finally received a little peace of mind that everything might just work out in the end :) the tech said she thinks it's a girl (my Husband may have had a mild heart attack) but we are not counting our chickens just yet. ;) I know nothing of skull theory, but what do you ladies think?
