Early pregnancy symptom or just something weird?

For the past 2 weeks I’ve been waking up pretty hungry which is unusual for me. Every time I get really hungry like this I start to have to gag. I don’t actually throw up, just can’t stop gagging unless I chew gum or drink fluids. It goes away a little after eating but sometimes it still comes back. It’s honestly so annoying and I’ve been taking tums which doesn’t help it at all. So, did anyone else experience this as an early pregnancy symptom or something?
