"Morning Sickness" reappearing 2nd trimester 🙊😷

I'm 24 weeks pregnant with our baby girl. In the first few weeks of this pregnancy, I would get nauseous at random times of the day with no throwing up. That went away around week 10-11 and I never had it again until about a week ago, it's been happening everyday again. 
When I was pregnant with my son, I didn't get even a hint of nausea even once throughout my entire pregnancy. 
Is or has this happened to anyone else?!   :(
