boy or girl??

Katie • Mon, Nov 07 • A 24 year old mama to a wild 2 year old boy (Oliver) & another wild boy due May 18th 2017 💙

I had my second ultrasound today - 12 weeks 4 days due may 18th! Any guesses on the gender? We tried to look between the legs but couldn't tell. Anxious! My son is 2 & fascinated so far.
