17 week boy????

Please help! Is my boy definitely a boy or is there possibility of change? This was 17 weeks 1 day. Too early? In the ultrasound, I kept seeing three protruding lines, middle one slightly longer. But I didn't see a scrotum or any convincing looking penis. I'm just confused. :worry:Attachment 24376Attachment 24375

If the tech said boy I would believe her... I just don't think that either of these pictures are good for gender.

Can't see gender in either pic.

Need a potty shot at 17 weeks. Not seeing any clues, sorry x

This the only potty shot I got. Not sure if is very reliable. Attachment 24388
