Morning sickness went away?

So has anyone else had days when you have absolutely no nausea? I've had the worst tummy aches and no appetite all week, I only threw up once but wanted to multiple times especially when I brush my teeth! But then I woke up today with absolutely no nausea or stomach ache.. Is there a chance my morning sickness just won't be that bad or am I having a good day? I'm just really hope it doesn't get worse soon! I'm only about 6 weeks, I've had morning sickness since the start of 5 weeks.
