No morning sickness...

I'm a FTM (and I may regret saying this) that will be 8 weeks tomorrow and do not have ANY morning sickness. Sore boobs, fatigue, sensitive smell (which sometimes turns my stomach)... I'm torn between feeling like there's something going wrong with my pregnancy & feeling thankful I'm not vomiting every day. We did have an early u/s & saw our little peanut with a beating heart but this is still causing me worry. Any advise or comments from some veterans that could set my mind at ease would be helpful.
