Is this a boy?

I’m sorry to ask but since I’ve shown people my ultrasound they say it doesn’t look like boy parts and it’s really annoying because I really wanted a girl. To me it looks like boy parts and I see no sign of a girl but I can’t help but still have some kind of hope. I will still love my boy but I just feel like I need to just get over it and I can’t if I continue questioning. Do you think this is an umbilical cord? I know this may be stupid to ask but please tell me what you think so I can just be happy I’m getting another boy and not dwell on never having a girl. I need to just except my reality I’m gonna be a mother to three boys.
