I'm 19+2, my bump popped at around 16 weeks and I can feel that the lower part of my tummy is hard but over the last few weeks I feel my bump hasn't got any bigger. You can't really tell I'm pregnant, I just look a little bloated and my old jeans still fit but I've see other almost 20 week bumps and they're very noticeable. I am plus size (size 16-18). I do feel baby moving a lot.
