Late period and don’t want to get my hopes up

Yvonne

I’m 6 to 7 days late. I’m never late. And my husband thinks it’s stress but I’ve had stress periods before and they’re either super heavy or super light. I ovulated on the 19th of last month and got some light spotting earlier this month and only bled for two days and I didn’t ovulate this month and now my period is late. I hate getting my hopes up but should I buy a test now or wait a little longer for my period to show up?
