MIL keeps saying it's a boy!😡

Hello all! I'm 38 weeks right now and pretty soon gonna see my baby girl. We had our anatomy scan at 20 weeks and we got a clear potty shot and it's a girl... but my MIL keeps insisting that it's a boy and she is so adamant about it to the point that I get so annoyed. Here is a pic of the ultrasound. I've shown this pic to my doctor too and she says it's as clear as day that it's a girl. And now my mom started this weird argument too that my belly does look like I'm carrying a boy... me and my husband have always wanted a baby girl and this is our first child. It's gonna be a really big shock for us if it's a boy but still we will be happy as all we want is a healthy baby. But it's really bothersome when people around us keep suggesting that we are gonna have boy time and again. Can you please take a look at this pic and tell me? It's a girl right???? Thank you!
