15 weeks gender reveal

Do you think it'll be accurate tomorrow at 15 weeks to find out my baby's gender? My nurse today was telling my MIL in law that it was waaaaay too early to tell at my dating scan at 14 weeks. But obviously they didn't even try or mention it. I saw something pretending outwards but I know the fetus female clitoris does that too . I'm finding out at 12:30 am tomorrow at goldenview ultrasound . Paying 60$ for the picture posted below .
