Ovulated later than usual

I must have ovulated later than usual but I distinctly remember my ovulation pain being around the 31st I'm now 8 days late for my period I had minimal spotting last week for two days (4/8-4/9) i took a test on Friday (4/11) only to get a BFN ! When should I test again? I have no AF pains just very mild cramping slippery CM a high cervix hunger pains in the am as soon as I awake and tender breasts and mild headaches through out the day ! Please any advice will be greatly appreciated
