Am I having a baby boy?! 🥺

Yesterday I went in for my NT Ultrasound at 13 weeks pregnant. I was getting the ultrasound done when my what seems to be my son was spreading and kicking the wand & the tech exclaimed “Oop I think I know what you are having!!” & I’m like HUH ( Thinking there’s no way I’m too early ) I look at the screen seeing what I think are male parts in between the baby’s legs. Keep in mind I’m having a gender reveal on the 1st of March. I was hoping for a girl btw. I’m not upset or disappointed, I am truly shocked that already I possibly know it’s a boy but also I found out so fast and without my fiancé ( He was 10 mins away and missed it) She said wait for the bloodwork to confirm however she seemed positive… I don’t think the surprise is ruined because I still need confirmation from the blood that it’s a boy, but it also could still be a girl right? Or does this mean I’m having a boy? **Attached photo, you might need to flip your phone**
