Finding out gender

Than keeping to yourself?!? So this baby is suppose to be our surprise baby. However I had an ultrasound and the tech was trying to get baby to turn over and was pressing all over and went right over potty shot very quickly a few times and I’m about 98% sure that I know what the baby is since I do know what I’m looking for since I have kids and worked at an obgyn in the past. I haven’t told anyone. Not even my husband. I’m also trying to pretend I didn’t see anything and convince myself I could be wrong. 🤦🏻‍♀️
