Pregnancy differences?

With my first pregnancy, I had borderline hyperemesis and was throwing up 6+ times a day every day before I even got my positive. I was also incredibly tired and just felt miserable. I’m currently 5 weeks 2 days and besides a strong sense of smell and sore boobs, I wouldn’t even know I was pregnant (these symptoms started reallyyyy early and I got my positive at 3 weeks 4 days). Anybody else have COMPLETELY different symptoms between pregnancies? I’m overjoyed that I don’t feel the way I did last time, but it also makes me a bit nervous because at least with my first I “knew I was pregnant” because I felt the symptoms. I’ve got myself slightly worried and overthinking! 😂
