15 week appointment coming up, OB says we will look for gender

So, I will be 15 weeks at my next appointment and my OB said we should be able to see gender by then on the ultrasound. Has anyone else found out the gender via ultrasound this early, and the ultrasound have been correct?

We are so very excited to find out but I do have a bit of anxiety about possibly being told the wrong thing. I just want to start shopping for stuff and finally call this baby it’s name. 😬🥰When I mentioned that to my OB he said they can tell pretty with an accuracy of around 95% at 15 weeks.
