Is something wrong with my babies head?

I noticed that my babies four head sticks out and was wondering if anyone else has noticed this on their ultrasound? (This is a 28week pic from yesterday)  I didnt even notice it until someone said something then I went and looked at ultrasound pics of my other 2 children and theirs do not stick out...is this something I should worry about? I'm going to ask my dr on my next visit but just curious if anyone else has seen this or asked about this TIA
