Different pregnancy symptoms

How likely is it to have 3 straight pregnancies with the exact same symptoms & nausea starting at 6 weeks on the dot and the next pregnancy completely changing the consistency??!! I’m 6w 1d now & should be full blown nauseous just like my other 3 but I’m totally feeling fine & hungry! Makes me nervous, but also very happy & grateful that I could actually have a pregnancy I can fully enjoy this time! I mean, I know each pregnancy can be different but this is not normal for me! The nausea could hit later maybe but hopefully not. Anyone have this experience with multiple pregnancies all the same, then 1 completely different with healthy babies??
