We had our 20 week sono today and we told the tech (who was lovely) that we didn't want to know the sex. When she finished and went to go get the doctor she typed some stuff into the computer and for  a split second an info screen flashed up that she clicked off of quickly...I happened to be looking and I'm a pretty fast reader and caught a glimpse of an info box with "Gender: F" filled in. When she left the room I said to my husband "I think I saw something I wasn't supposed to see..." I filled him in and he was like well, we still aren't sure, maybe that was your gender, not the baby's (which I found funny, since I don't think men get sonograms for expecting babies but maybe they need to fill that in anyway)...but I don't know 100% what I saw. I've been convinced I'm having a girl anyway since day one, and it doesn't matter since my baby appears totally healthy and I'm thrilled no matter what. But has anyone found out the gender accidentally this way or otherwise? :) just curious! Thanks!!
