Feeling Well?

I'm 7 weeks 2 days today and I feel fine. I've had maybe 2-3 days during the last few weeks that I've felt even a little bit pregnant, slight nausea, minor fatigue, not much. Anyway, so I've seen the heartbeat and my baby is measuring well and I still feel fine. Is my lack of symptoms a sign that it's unhealthy? Or is it that I'm just lucky and feeling well? Or is the worst yet to come? I'm waiting for the symptoms to get bad, but they just haven't.
