Rockstar - AshnAmber and I were just discussing this a little up on this page. Yes - I've never had a TON of symptoms, but the symptoms I have had have been lessoning over the past week or so. My boobs may be sore one day or not at all another. Although I'm still tired, I'm not falling asleep at 8:30 like I was before. (to be fair, my pregnancy exhaustion could be completely gone and I'm not noticing because the 3 month old we're caring for right now has decided she doesn't want to sleep at night anymore.)
Having symptoms or not having symptoms is totally normal. I know it's hard to trust but we just have to have faith that, barring any spotting, everything is going well in there. I had my last scan on Friday when I was feeling completely normal (ie not pregnant), and saw a perfect little bean bouncing around in there.
