When the heck is this bump coming??

I am 13 + 5 with my 3rd baby. With my two boys before I thought for sure I had a little bump started by now but with this one there's nothing! Except for when I wake up in the morning with a full bladder, then I can feel a hard lump all the way up to my belly button. What the heck?! When is this bump gonna make its appearance?

Hubby thinks that maybe this one is a girl and that's why it's different than our two boys.
