Super upset!!

My husband and I decided we wanted to wait to find out the gender until baby is here. Well I had to have an ultrasound yesterday because I’ve been bleeding and they wanted to see where it was coming from. Well I didn’t want to look at the ultrasound at all just Incase the tech accidentally put it over where the gender parts would be but the tech said “oh look how cute the profile is!” and so I looked and then baby moved and I swear I think I saw a penis and though I’m overjoyed if it’s a boy I’m devastated that I might have ruined the surprise 😭 has this ever happened to someone? Could I have just seen the umbilical cord?
