First symptoms?

My period is 6 days late, I’m crazy emotional, I’m tired, confused and nervous. While I think I’m pregnant, I refuse to take a test because I’m terrified of actually knowing (I want a child but I am not at a stable point in life).

I was wondering what everyone’s first symptom was/ what other than a test/exam made them know?

(I’m not looking to use this as clarification, I’m aware the only way I’ll know is a test, I’m just looking to see if it’s worth buying a test or waiting my period out)

Thanks in advance!
