Is it a he?

Jessica
I went to my Drs appointment the other day and the nurse asked if I knew what I was having (I'm 25 weeks). I said no, it's a surprise. Later she was having a hard time finding the heartbeat because baby had the hiccups and the dr said something like "he's over here". I know a lot of people just say he no matter what. Maybe I didn't really hear that?  I don't even know if they do know the gender since I didn't find out.  What's you guys opinions. I haven't told my husband bc I'm sad I heard it myself.
