No morning sickness yet is this normal?

This is my fourth pregnancy and I am 8 week 4 days. By this point I expected to be severely nauseous and not being able to hold anything down. Is it normal that I am not nauseous at all I’m just hungry all the time. With my previous 3 pregnancy’s I was so sick from about 4 weeks until 20. Borderline HG. Like I could barely function and it was awful but I knew it meant healthy pregnancy. Now I keep getting out of pocket ultrasound (3) to make sure I am still pregnant. I called my midwife and she said every pregnancy is different. As long as I don’t have cramps and bleeding I should be good. Anyone else experience completely different pregnancy’s?
