Morning sickness in 3rd trimester?

Lindsey

I never got sick in my 1st or 2nd trimester and now I'm almost in my 3rd and I have felt nauseous the past few mornings.. I ate something yesterday and the day before and felt better but this morning I didn't eat and started throwing up in my car on the way to work. Idk if it's morning sickness since I've never had it. I've never heard of someone only having it in their 3rd trimester.
