Should I test yet?

Mimi • Momma bear 🐻 expecting her second cub💙.
I was up early this morning at 4 am for a hour throwing up and having heartburn. Nothing I ever felt like before then my stomach was playing tricks on me thinking I had to but then I'd just burp. It's been 9dpo and I've spent so much money on tests and got false positives or just negatives before I don't wanna get my hopes up? What does pregnancy throw up feel like because now I feel perfectly fine! What should I do?
