Not sick with baby #2?

Bri

With my first son I was extremely SICK from week 5 to week 18 (throwing up 2-3 times a day), extreme fatigue and breast tenderness.

With baby #2 I am 6 weeks 1 day and the only symptoms I have is fatigue and breast tenderness.

Anyway, is this normal? I have a telemedicine appointment in 2 weeks so I can ask my doctor then but does anyone else have experience with having little to no symptoms with baby #2+?
