nothing to do with ttc but I need to ask

So I just had tea, I took my kalms and had 2 glasses of water with them I run back upstairs, bend down to pick up something from the floor....I burp or what I think is a burp and throw up, it's like the tiniest bit in the world and it was really cold because I'd just drank my water...should this be something to worry about
I don't and didn't feel nauseated or anything like that...so strange, any help??
