At this stage there is still a chance it could be a boy, but it looks pretty girly. My DS2 at 16 weeks we had an US done and at one point I saw a bulge and I was like oh it's a boy and then the doctor moved the wand and we saw 3 lines, then I was confused. LOL But at 20 weeks he was all boy! But with yours I would be inclined to lean more towards girl :)
