I don't think your that big at all. Very cute bump if you ask me 
I have no clue on the gender though, I have carried different in all my pregnancies and I have 3 boys so far.
Good Luck!

"Boys are meant for kisses and hugs, For watching rainbows and catching
bugs, For sharing all of your favorite things, For books to read and
songs to sing. Blue jeans and trucks, scrapes on his knees, Running in the Dirt, and being a tease. Making a face, and build and destroy. There's nothing like just being a BOY!" ♥♥♥♥
