Should I test?

Okay...I was late on AF by almost 2 weeks. When AF came, it was super weird. For 2 days I spotted only when I wiped, dark old blood. It stopped for two day and began again. After one day of that, I had a mixture of regulator blood and old blood. It was a moderate amount for about four or five days. During this time, I tested off and on and got all BFN. I'm officially off of AF now, but my boobs are still sore. Am I going crazy or should I just test again for good measure?
