Gender at 12 weeks?! Helpppp

Jordan

When we had our 12 week ultrasound (internal) the doctor asked if we wanted to know the gender, we said yes and he moved the wand to reveal it was a boy! 5 weeks later and I read how that could have been the umbilical chord and that it was too early. Meanwhile I have been shopping for a boy for 5 weeks now 😭 please tell me this is accurate. I have my anatomy in 3 weeks but im tempted to have a private scan to confirm, Im so paranoid now. I really don’t think the doctor would have showed us if he wasn’t sure, I have friends who go to him and it’s not typical of him at all to do.
