Yes, this occurs! Some women are just very lucky. There's also a chance that you will experience it later on. It can even disappear and then come back.
I'm 8wks 2days and I've literally only had nausea once, it lasted for about 5min and went away after I drank some water. My ob and the ultrasound tech both told me how lucky I've been.
Sounds like you’re one of the lucky ones! I had horrible nausea, vomiting and food aversions with my first pregnancy; I lost weight in the first trimester because I was so sick. It was misery but eased up by 14 weeks. This pregnancy has been a breeze in comparison with only mild nausea that comes and goes. I know it can be disconcerting to not have the symptoms you’re expecting!
Re: 6 weeks 6 days - no nausea?
Don't wish for something you don't have as it could possibly pop up at anytime.
