Rainbow - just stared at it for a good long while and I obviously don't know if it's a nub but I'm not sure what else it could be. Maybe just like how some nubs show almost as just a pencil thin line because of the placement of the wand, this is showing in a more chubby angle. The skull shape is also boyish, but we know that's not nearly as accurate as nubs. I definitely agree that it's super early and nubs aren't always reliable but I'd probably *myself* just assume boy from everything and then maybe be surprised later on. I'm seriously not wanting to sound harsh or anything because I'd love that to be your DD, but I'm just thinking what would be going through MY mind if it were my picture. Again, I'm not an expert nub-er but just from seeing everything on the site I know how it goes. They are all so different so it's seriously really hard to know! I don't even know what gender My baby is - no nub shot or any clues from 20 week scan and I'm grasping at straws thinking how it could possible be a girl after my super strong girl sway turned more boy sway the month I got my BFP. Like everyone I still think there's a possibility of this being your girl because I don't know how much I trust nubs!!
As I side note.. I do have to say that random floating thing on the left looks more like an upright penis than your nub does :)
