Ultrasound gone wrong ??

MomLove

I’m 16 weeks now but I went to get an ultrasound last week to get the gender at 15wks. The lady struggled about 20 minutes to figure it out and said I was very dehydrated and that made it very difficult to tell. She also said that since the umbilical cord was in between the legs she couldn’t figure it out. Then came back and said it looked like a boy but should I go boy crazy or try it again later? Has anyone gotten it wrong?
