Stubborn baby 😭

I was so anxious to go to my appointment this morning because we were finally learning the gender. First of all I got there 10 minutes early and they took me back right away, I told them my mom was on her way still and that I wasn't scheduled yet. Well the ultrasound tech wasn't having it and wouldn't wait so he told me to lie back and we'd do it without her. I was already upset, and then the baby was rolled into a ball, the worst position the tech told me. He really didn't even wait to see if it would move and just said well we're gonna schedule you to come back in a month. That made me even more upset because we were going to do a gender reveal, and we really wanted to know so that I could have my baby shower early before I move with my soon to be husband. I'm so disappointed that we didn't learn the gender today. I feel like this next month is going to be so long, and my fiancé won't even be able to go that time either. Did anyone else go through this??
