Am I pregnant

Ok so the 12-18 was my ovulation week but my actual ovulation day was on the 17th . I had unprotected sex on the 13th . My period was supposed to start two days ago. But through out the week before my period was supposed to start I’ve been cramping thinking ok my cycle is about to start I even had a little brown discharge but yesterday on day one of missed period I had no brown discharge. Now I’m on day two cramps are very light so I barely feel them. Could there be a chance I’m pregnant I’m so confused with the cramping and discharge
