I had my second ultrasound done on the 11th at 17 weeks and the tech said she was about 95 percent sure its a boy. This is my last baby so my doubts are only because I have 3 girls and this is still a shock. She tried so so hard, for more than 30 minutes to get this stunborn baby to show the goods so her determination tells me that she really went above and beyond to give me a pretty educated answer. She also lit up the umbilical cord to make sure the shot she had wasnt the cord by mistake. What do you think?
