No morning sickness

I have no sickness at all. I was deathly ill a few weeks ago (throwing up every hour on the hour), I thought it was morning sickness but it was a stomach flu (I had a fever and chills too). 
I have no sickness besides very occasional mild waves of nausea. I don't have any real food aversions either. 
I know everyone will say I should be grateful but it makes me feel not pregnant and I'm nervous. 
I was exhausted for three weeks but now at 8 and a half weeks I feel my energy coming back. 
Should I be worried something is wrong?!
