Gender at 13 weeks ?

Abby
Hi ladies !! Has anyone found out the gender of their baby at around 13 weeks ? I have an appointment Friday for first trimester screen and the baby will be measuring 13+4 and I was just wondering if they would know or could see that early ? I have an appointment made at 15 weeks for a gender scan but maybe I won't have to ig they can tell me now. Thoughts ?
