Scared to test

Jessica
Ok ladies.. I ovulated on the 19th. For the first time I had that awesome ewcm i have heard so much about with a little blood in it. I am now 5 days late for my AF. I test on the day my period was due, it was negative so I figured that I would just be starting later that night. Not so much. But I have had so many BFNs that I am scared that I am going to curl up in a dark corner and cry if it's negative again. When do you think is a safe time to test to get a real result?
