10wk ultrasound doctor assumed gender ??

Kayla

During my ultrasound for 10wk my doctor looks at baby's wee bits and said well 60% bet it's a boy but still 40% girl so more likely boy. Of course I want a baby boy I would be over the moon but I doubt you can make these assumptions so early he went based off the ultra sound I'll tag below the plus sign is above what he thinks will likely be wee boy bits. this is between leg shot . Obviously not getting my Hope's up but what are your opinions?
