ANYONE HERE AN ULTRASOUND TECH?!

N
I got an ultrasound this past Tuesday at a place called Motherhood. Since I won't be getting one until my anatomy scan, I wanted to see how baby is developing since week 5 (first time I saw him/her) during the ultrasound, the techs seemed to think they might have saw two babies but when inquired, one of them brushed me off saying "sometimes it can be an artifact" wtf?! My mom caught it on video. Anyway, anyone of you ladies an ultrasound tech or know of one who I can get to review the video? If love an opinion on whether or not you think it may be twins!
