I am ashamed to say I still haven't taken any bump pictures. :(
I am about 5'7'' and 207 prepregnancy. I lost some weight initially and am back up to 205. My jeans stopped fitting around 10 weeks and I had to switch to maternity jeans (or sweatpants, which doesn't appeal to me for going out and about). I felt kinda silly then because I didn't really have a "bump", probably just bloat. At 21 weeks, I feel huge now, and definitely look pregnant. The first time a stranger commented on my belly was 17 weeks.
One thing that has surprised me is the lack of stretch marks. I had just a few (4?) faded ones around my belly button prepregnancy, and so far only have noticed that the very tip of one of them has darkened a little. My mom didn't really get stretch marks during pregnancy, so I'm hoping I get that from her (even though she was super tiny, only about 100lbs before she got pregnant). I definitely didn't get her figure!
I'm still wondering when (if!) my belly button is going to pop!
ETA: I should have mentioned, prepregnancy size 16.
