Feeling better in pregnancy (15 weeks)

I've inherited some pregnancy books from good friends, and all of them pretty much say that I'd be feeling better by this time. Wow, they weren't kidding. I'm pretty much feeling the same as I did before all the hormones took over and only occasional nausea (usually due to indigestion which is very normal). Smells that really bothered me—i.e. fried stuff, certain perfumes—don't put me in the state of nausea anymore either. Kewl beans!

I should have done this as soon as I found out I'm expecting: tracking the size and depth of my evolving belly button innie. It's definitely 2x it's width as it was 2-3 months ago, and I can see the bottom of the crevasse for the first time.
