8 days late

A year ago my period was 12-15 days late and I tested only to find it was negative. My Periods been regular & ON TIME all 2020 so this has me nervous a lil. Tender boobs, slight cramping and slight heavier than usual discharge. No nausea so sadly I don’t think it’s pregnancy 💔could just be me ovulating later than usual?? Please share positive similar stories as well.
