Symptoms disappeared over night

I’ll be 9 weeks tomorrow and for the last week or so I’ve had such bad nausea, headaches, fatigue, dizziness, hunger etc. I’ve woke up today feeling totally fine. No symptoms whatsoever! I don’t feel like I’m pregnant at all, I had a missed miscarriage last year and before I found out the heartbeat stopped (same day) all of my symptoms disappeared so obviously panic mode has begun. Is this normal? Shouldn’t I still be super nauseous? :(
