Twins or just 1?

Estelle

I had my first ultra sound this week (abdominal) and we saw baby and baby’s heart beat ❤️ the sonographer had me empty my bladder as I was too full and wanted to look again, she said she wanted to check for 2 but then said nope just 1. I have had a few people tell me this photo makes it look like there’s 2 though! What are your thoughts?!
