Skinny mamas: when did you start showing?

Maddie

I've been reading that thin ladies often show earlier so I'm just curious to hear your stories. I'm of average height but naturally very thin and considered underweight. My stomach has previously been pretty flat and I don't have any fat in that area. I'm 10w2d so too early to be truly showing but I've got a decent bloat bump at the moment! Just wondering when other thin ladies started showing for real?
