Symptoms Disappeared

Me

I'm 9 weeks + 3 days today and for the past few weeks my morning sickness was through the roof, I could hardly function, I couldn't touch my boobs, I was constantly nauseous and felt sick until yesterday, when I woke feeling like a million bucks and cleaned my whole house because I felt so great. This morning I still feel pretty good. Anyone else have this sudden change? Should I be worried?
