the ultrasound from yesterday was in my head the whole night... I googled boy fetus at 14 weeks that looked exactly what I saw and the tech was doing it was the spine.. it is most definitely a boy.. I have 2 girls I know how the girls would look like. it is a boy!!! I'm still waiting for my 20 week u/s but I already know!!! lol at 12 weeks the genitals for both genders are forming at that time so by now it has a shape.
