Unsure

My last period was February 24. I went to the Dr last Monday to get a second opinion about possible PCOS ( he said i didnt have it! Yay!!) and I told him that my period came 10 days early. I told him it wasn't like my real period. Thick brown and some dark red for 3 days or so. He told me it was ovulation bleeding and I should expect my period sometime this week. As of today still no period. The last day we had intercourse during what I thought was my fertile time was the 14th. Any insight?
