Do girls make you sicker?

Kara • Pregnant with our second and final Peanut. Our first is only 1 year. This is going to be one crazy ride!!
I've heard that girls tend make you have morning sickness worse then boys. I'm wondering how accurate this is for everyone.  How long did your morning last/is lasting? And are you having a boy or girl?  
I'm 20 weeks pregnant and still sick 💘💘💘💘💘💘
