Well ... if it were me I'd want honesty. I know people (and husbands) are being supportive when they say "nooooo ... you're imagining it" but I know that there are times that you need someone to say - yes, you're not crazy or being weird or obsessive. So I'll be that person!
I do see a little tummy. I don't see a BAD belly, and certainly nothing I'd be ashamed of if I were you, but there's a little bit of bump there. (and that's from someone who has more than a little bit of a bump and is really wanting to get rid of it and who isn't about to post pictures of herself yet ... so take that for what it's worth!).
I've heard, read, been told by my doctor and others that belly fat is just really hard to get rid of and the ultimate last to go.
I've also heard, read, been told that simply focusing on abs exercises doesn't remove belly fat. It does is firm up the muscles *under* the belly fat which will make your abs look great when the fat is gone. But the only way to get rid of belly fat is to burn it off with exercise and reduced calories.
It looks like you've already lost 30+ lbs and are about 7-10 from your goal - and it seems to me that the last 7-10 lbs are the ones that are going to make that difference with your tummy.
I'd just keep doing what you're doing.
