Gender at 14weeks

So I’m finding out the gender of my baby this Friday. I’ll be 14 weeks and two days. My friend did the same and found out the sex but as the days get closer I’m growing nervous. I’m scared they won’t be able to tell us and I have a gender reveal for my family and friends the next day. So I’m kinda scared everything will go wrong. Has anyone did the early gender reveal at 14 weeks. Was it accurate. I have 3 girls so I’m so anxious to see, I want to hear your stories to ease my mind.
