Late period test or wait?


I think I might be sick but then again I’m not sure. I’ve been throwing up and feeling nauseous for 5 days now. I can barely keep anything down and yesterday I pooped so many times kinda want to say it could have been diarrhea. I’ve been dizzy twice now and almost passed out both times. I tested on the 7th and 8th and both were negative. I want to test again but don’t know if I should just wait it out or not?
