Bump this early?!

I haven't been to the doctors yet (not for another week) but according to my LMP I'm 8+5. Is it normal to have a bump like this this early?! There are so many twins on both sides of our families that I'm nervous there are two in there! Also it's getting tricky to hide it! Maybe it just bloat? It's getting bigger and bigger though! What do your 8-9 week bumps look like?
