My husband was doubtful so after our ultra sound we saw the doctor to review some of the results. The Dr confirmed that indeed we were having a girl. However my husband asked her 5 times!
Well it'd be hard for you to tell since you are even less use to looking at the images than the technician. I know I couldn't tell hahaha. Why not ask your doctor if at the next appoint they can go over the images with you? The woman I had was new to fetal ultra sound but was well versed in other fields like sports injuries. So I had another nurse with me to help her out so I thought two heads are better than one! But I bet she did a fine job and if anything just speak with your doctor next time you come in for an appointment :3
