Second Trimester Morning Sickness

Catrina • 25. Married to my other half. 5-15-15. 1 angel baby named River. Daughter named Remington. Son named Journey.
Is it possible to get morning sickness in the second trimester? I was fine with my last pregnancy and even this pregnancy up until today. 
I'm 16 weeks exactly and I feel like total shit today. I have been nauseous literally all day. Every smell makes me want to hurl. I don't know if it's a virus I got or if I'm just now experiencing morning sickness. 
Any idea?
