Honestly I'm leaning more towards a boy, only because it looks like the placenta (the thick white area at the bottom of the sac) is growing more on the left side of the sac, which if you flipped it since it is a mirror image would make it actually on the right side of your body. You go with where the placenta is growing for Ramzi, not where the baby is laying. The baby can move anywhere in the sac. Also I heard that sacs with boys are rounder whereas with girls it is more oblong. I don't know how much that is true though. I do hope you update when you find out because I admit that yours is one of the harder ones since it is in the middle LOL!
