I went in for my 2nd ultrasound on Friday. This was supposed to determine the sex. Well, the baby's legs were crossed the whole time and I heard this is my last ultrasound till birth. Is that true? The ultrasound lady wasn't really nice either. I asked how it was going because she didn't say a word to me and she said "I can't say anything, the radiologist will send the information to your doctor." Do you really only get one shot if the sex?
