I went to my 14 week ultrasound and the ultrasound tech was trying to see the sex of the baby for like 40 minutes for pushing and Turning she just couldn't get a good picture I ask her 3 times what she thought it was but she was so unsure she didn't want to tell me afraid she would give me a wrong answer.. as I was walking out I asked her again and she was like I think girl but please don't buy anything and just come next. Has anyone been thought is? I have two girls already hoping it a boy I feel like it's a boy.. has anyone had problems with ultrasound..?
