Family gender disappointment

Has anyone had to deal with their families being disappointed about your babies gender? I never even thought this would happen. My mom, aunt and grandmother said they KNEW it was a girl from day one. Yesterday we revealed were having a baby boy! They were initially happy but now they keep saying things like "the test can't be right. It's a girl" which is definitely not true cause we found out by chromosome testing lol or "maybe it's twins and the other is a girl!!" And it's driving me crazy. 🙄 has anyone else had to deal with this?
