No symptoms....why?

So I am just a tad bit over 6 weeks and I really don't "feel" pregnant. Other than having very sore boobs over the past couple of weeks, I don't have any symptoms at all. I didn't have morning sickness with Melanie or Aaron and it's looking like I'll be fortunate enough to slide by w/o it with this one too-but darn, I'd at least like to have "some" indicator of pregnancy so that I can stop worrying...I really need to get off the Internet-WAY too much negative information out there.
