I'm only in my 9th week but I've noticed that my morning sickness have been much more mild then my others. All my other have been normal, like hot flashes and breast tenderness. I'm wondering if this could be a girl

Because with both of my girl pregnancies, they were mind. My first was by far the easiest, where I had a week of mild nausea. Since I didn't know I was pregnant at the time, I passed it off as food poisoning. LOL
Is this typical of boy/girl pregnancies or gender doesn't matter?
My first ultrasound should be around the 18th week, so I can play the guessing game till then.
