Morning sickness

It's way too early to test or know for certain, but I've been having issues for the past 5 days or so with keeping food down in the morning/early afternoon. I eat a few bites of food then throw everything up. And certain foods trigger gagging in me that never did before. This is unusual for me bc I have a VERY strong stomach. Like I don't even throw up much when I have the flu or food poisoning. Could this be morning sickness?
