Boy or girl? First time mom

Hey mamas! I’m 38 I’m 9 weeks and 2 days. This is my very first pregnancy and me and hubby are over the moon excited. I’ve seen a lot of mom groups post regarding the ramzi theory. Not sure if it’s to late to determine the sex of my baby but I wanna give it a shot! I posted 2 photos the bottom bobble is the yoke sack and that line under is the fetal pole. Trans vaginal Any guesses?
