Lack of symptoms cause for concern?

I'll be 9 weeks tomorrow, and just in the past few days, my boobs have stopped being sore and I'm not nearly as exhausted as I have been. No cramping, spotting, or anything else out of the ordinary. I miscarried last year around 8 weeks (with no symptoms beyond excessive cramping early on), so I'm very anxious about my first appointment. For those who have been through it, is the sudden absence of symptoms a cause for concern, or is it normal at a certain stage in the first trimester?
