Different symptoms with baby #3?

I'm currently 5w3d with baby #3, and I'm noticing that my symptoms are a little different to my other 2 pregnancies. With both my daughters, morning sickness started around about now; and hung on firmly until 16 and 18 weeks, and in full force 🤢 It was worse with my second. This time around I've been experiencing rolling nausea for about 2 weeks now, but have only thrown up 3 or 4 times. Not that I'm complaining of course!

Has anyone else had different symptoms with a third pregnancy?
