Throwing up out of practically no where

So as of midnight (a few minutes ago) I'm 11 weeks in! Exciting being that Nov 2020 we got pregnant after our first try which was confirmed about 5 weeks later to be ectopic. I've been lucky this second time around with our rainbow baby. I've had very slight nausea once in a blue moon and then one morning as I spit out after brushing my teeth I just threw up 2-3 times. It wasn't stomach acid - very mild - but it caught me by surprise because I wasn't nauseous before or after. Today, maybe 2 weeks post this experience, I just violently threw up for maybe 15-20 minutes after eating something small. No nausea before or after. Ugh. Is this normal?!??? Has this happened to anyone else???
