is this a cleft lip?

Victoria

So tuesday i went and got a ultrasound done and im freaking out now because as i look at my sons 3D pic more and more his lip looks like it has a cleft in it? Im not sure and my mom is saying " no maybe thats just how the picture came out. The dr would have told you . " My dr said he has all 5 fingers and toes and everything looks great, and im very grateful it is but his lip looks a little weird. What fo you ladies think ? Am i just freaking out for nothing and seeing things??
