What is this?!?!

So I'm 13 weeks pregnant & I keep experiencing this weird feeling beyond what I've ever experienced. I want to so bad say it's nausea but not sure sure. I only experience it when I inhale. It's like a cool sensation. Like if you ate spearmint gum then drank water, that cool sensation. But it just constantly happens when I inhale. I haven't thrown up but it feels as if I should but nothing comes up...

any ideas what this is or what can I take to help STOP it?

Thank you.

The extremely sick & annoyed pregnant lady 😩
