Here again

Alright ladies, I posted a few days ago because my period was two days late, and I didn't know if I should take a test then or wait. Long story short, I took a test, and it was negative. I am now 5 days late, nauseous, & have just felt like crap all day. Like, just kinda drained, a minor headache since I woke up, my stomach is upset off & on, I'm having some hot flashes. It pretty much feels like a hangover, except I havnt drank anything. Should I take another test? I'm so sick of feeling the dissapointment of a negative test. 😒
