Speculation! Is it a boy?

Okay ladies, this is my ultrasound from Wednesday at 12w3d. Tech said it was too early to speculate as the baby's genitals are still swollen this early which I am completely okay with not knowing yet. But I was looking at my pictures again and noticed a little nub right between where the baby's legs are...am I just seeing things or could it be a boy?

*This is just for speculation and a little fun as I won't find out for sure until my anatomy scan in early February*
