Ultrasound question

Am
I'm a ftm and I am about to be 16 weeks. I have an appointment on Monday to monitor a cyst but they always switch it to let me see our little peanut. They only do transvaginal ultrasounds and I am really hoping we might get to see what the baby is early. Has anyone ever found out the gender by a transvaginal ultrasound? Just wondering. Thank you :)
