Positive opk 13 dpo

Hello, everyone! I've been tracking my cycle using opks and I for sure ovulated April 13. And got a strong positive opk April 12 then continued testing the next 3 days, the test line got fainter and fainter into a negative. But I've been having lotion like cm, sometimes ewcm which is not common for me later in the cycle. Today, after I wiped this morning there was pink blood in my cm and cm is really like egg white but whiter and pinkish. I don't have hpt but I have opks lying around so I thought whatever I'll just pee on one. And I got this positive within 3 minute mark. Test line is darker than control. What does this mean?
