Lack of a bump!

So I thought I popped a bump at 12 weeks but it turned out to be bloat and everybody noticed I was pregnant and thought it was a bump too and I was like ya dunno I guess genetics! Lol now my bump is deflated and I can't figure out when I will get a true bump! I'm 13 weeks! And I actually lost 3 lbs from my last visit two weeks ago with the dr isn't that backwards!!
