Girl or Boy?? 20 weeks anatomy scan

Today I had my 20 weeks ultrasound, everything is good and baby is healthy and growing😄 , at the end the tech try to look for the sex of the baby, she saw this picture and said "there's the 3 lines, you are having a girl" so I went to buy some cute pink outfits, later at home DH was looking at the pic. and said "I think she got it wrong" , I am happy either way, girl or boy but I don't want to go crazy buying pink girly stuff and then have to return everything, so what do you guys think, girl or boy?? Thank you in advance for your opinions 😊
