5 Positive OPK's a few days after "suspected ovulation"?

I have gotten 5 positive Opk's since my scheduled ovulation date (test line darker than the control line). I tested again a few moments ago and it is FINALLY negative. I also have a few symptoms that started since 3 DPO. They are very thick creamy cm, I had headaches, dizziness and backache from 1-3 dpo. I'm having sore bbs and loss of appetite at the moment. What does this all mean to you? HELP!!!!
