Vanishing nausea ???

Lauren
I am about 6 weeks and I've had bad nausea and dry heaving for 2 weeks. Lots of smells would upset my stomach too.
I woke up two days ago with vanishing nausea. I feel normal again
I am not complaining !!! But is this normal ? I am not bleeding or cramping so I don't see any signs of miscarriage .
Any advice ?!
