Should I test?

Started my new pack of pills after being off them for a while on the first day of my period last month. I have had sex numerous times unprotected after my period stopped. I just read that you aren’t protected if you start the pack during your period and should still use backup. Pcos usually causes my periods to be irregular but I lost a lot of weight while off the pill so my periods were beginning to be regular. Fast forward to this month and I’m 8 days late, eating all day and just tired and cramps. Should I test now or wait longer?
