Question?????????? A little TMI

I know this sounds dumb but I believe I ovulated around the 17th of this month I had egg white cm heavy on the 17th and medium the 18th and light on the 19. I was late on getting opks and I took it on the 21st and it was almost positive and for two more days it got lighter and lighter till for 3 days there was nothing on the opk test well I took one this morning and now there is another line it's not a positive opk but I am pretty sure I already ovulated earlier around the 17th . My period is due in 6 days. Could this mean anything? Or am I over reacting?
