I had a 19 week ultrasound yesterday. At first I was told was told I was having a girl we saw the 3 lines, she checked again still a girl. There were pics with the arrow saying it was a girl. After the scan was finished I asked her to check one more time. This time there was a penis, no lines. I now have an it's a boy pic. What???? Could it be twins? What were those lines? I called my midwife but she hasn't returned my call yet. What would you do? Oh, the baby was very active and flippy the entire time the tech had a hard time getting the measurements because there was so much movement.
