No symptoms

I have essentially zero symptoms. Some fatigue, maybe tender nipples and a couple days of nausea but other than that nothing. I had some cramping week 4 but it was dull and intermittent. I’m 6 weeks 5 days right now and struggling to believe that this is a healthy pregnancy even with no history of miscarriage. Anybody with me? Anybody? :( just can’t wait to get that first ultrasound in 2 weeks!
