horrible morning sickness and then none!?

Jaclyn
My morning sickness is fluctuating so hard it freaks me out. Some days ill just get waves of nausea. The past two days I had severe nausea with dry heaving ALL day. And today I woke up feeling amazing. Fluctuating symptoms cause me so much anxiety. Anyone else have this where they feel horrible one day and great the next? I obviously would rather feel good than bad, but days with minimal symptoms then lead to anxiety.
