I swear you can't tell with bumps - mine have all been the same (1 girl, 2 boys).
But, I reckon it looks more boyish to me.
Having just said that I don't think you can tell, all the people I know who have had boys this year have actually been quite spread out in front, and those that have had girls have all had very pronounced bumps, but that might just be their figure and not putting on much weight/not being as big in the first place.
Don't listen to me, I have no idea. I try to guess every time with mine and always get it wrong!!
Hope you are able to find out and put at least me out of my misery!!
