Early symptoms

I am supper dizzy, moody, and only hungry for fruit or protein. I thought I had my period 2 days early but, it only lasted 2 days and was very light. My last pregnancy I bleed a lot due to PCOS. Iv had there's symptoms for 3 weeks now. Should I wait 2 and a half weeks or should I test now? What do you think? My glow cycles have never matched up with what my body was actually doing.
