I need your thoughts...

So I’m 11dpo. I took a pregnancy test this morning, and negative😞

But here’s the thing...I just feel pregnant! I have back pain, I’m exhausted all the time, nauseous, and even threw up 2 times, and I don’t really have an appetite. Is it possible that I’m still pregnant? Should I test again when I actually miss my period? I just need some hope...🙏🏻
