Confused about ovulation , first time something like this happen

So I tested on 11CD ( which is usually my peak day) i got the control line as dark as the test line

Then the next day tested again and the test line was darker this is normal right?

But then day later i was in pain like sever pain and so much blood i was bleeding to the point that I felt I'm having a second period in the same month the blood was dark at first with clots and then turned to pink and red then slowly disappeared ( one day bleeding)

I tested the other day after bleeding stopped and ovulation were negative.

•i know the bleeding could be because of the hormonal changes but the amount!!?? And the Pain !!!
