Symptoms subsiding/worried

I'm just about 7 weeks and was feeling pretty rough with the nauseous ness.  But last couple days it's been less and less.  I almost feel good today.  This worries me because this is exactly what happened when I miscarried around the same time.  I've also lightly spotted but I had that both with miscarriage and my daughters pregnancy.  I'm calling doc on Monday but can't really do anything before unless something significant happens.  So what I'm getting at is has anyone had symptoms subside this early and everything be okay?  It's feeling all too familiar.  Thanks.
