Symptoms during pregnancy

I'm currently 9w3d with twins. From 4-7.5 weeks I had some nausea, food aversions, and extreme fatigue. All of a sudden it's all gone- I am still tired but not as much and no nausea at all. I've had 2 ultrasounds and my babes are fine but it seems weird to me to not have any nausea anymore especially with twins. Am I making a big deal out of nothing??
