Officially 3 days late, advice please

Ana • Mother to 3 beautiful girls and 1 handsome little man.
AF was suppose to arrive on the 9th I've had cramps like I usually do but still nothing. Weird thing is that on March 4th(5 days before AF) I had EW discharge so I took an ovulation test and it came back positive we BD that night... So if I did actually ovulate on the 4th that would make today 8dpo. I'm so lost right now as to what I should do. If I actually ovulated on the 4th when should I expect AF and when could I take a hpt
