Aww Chele, I'm so sorry you still haven't got the bump you'd hoped to have by now.
I must admit though, that looking at your last picture I actually think that a large part of your bump is what you see as the 'B' part. Your little one is quite high up right now and from the little bit of skin that I can see underneath your ribs your skin is very tight there making it look like 'bump' rather than just 'B'.
It's a lot easier to look nicely pregnant when fully clothed than when showing skin. Have you tried messing around with different types of maternity underwear, pants, belly bands and tops? Try taking some photos when wearing clothes and adjusting the tightness of the tops by hand... it's what I tend to do for my bump photos, normal ones don't look quite as neat.
I know that my shape isn't the same as yours, but naked I don't look pregnant either (apart from the massive and many stretch marks). The only thing that makes me look 'pregnant' is that because the baby is so high up now (I'm 5 weeks ahead of you, so that -will- happen for you) the top of the B has gotten so large it now looks like 'bump'. I'll send you a PM with a link to a picture, please don't share and I'll delete it in a couple of days as I'd rather not keep it online =) . I know it probably won't be much to help you, especially as my shape is so different from you ... but just wanted to show that even though with clothes I look pregnant without them it's definitely not the neat bump that it can look like with clothes.
Now, for my 33 week bump while wearing a bunch of stuff to try and pull in the correct places. That means...
Tight stretchy maternity underpants that tuck in under my bra (-Need- them)
Over the bump maternity pants, stretch tight material ... has to end over the B line, never under or on as that will split my 'bump' in half
Tight Bump Band, same rules as the maternity pants but worn slightly higher
