Never throw up??

I haven't thrown up since I was 9. I'm 7 weeks pregnant and last night I woke up at like 2 AM and immediately felt like I was going to vomit, like cheeks tingling and everything, so I run to the toilet, only to salivate a bunch and literally drool all over the place, and then I felt fine. I guess I'm glad I didn't puke but it's weird to me. I'm like incapable of throwing up it hasn't happened in so long maybe my body forgot how to do it lol. Has this happened to anyone else?
