Ovulation Bleeding

Sunny
I started spotting on 6/5 and also had a positive OPK were the test line and control line are the same. Than on 6/6 still spotting but the test line for OPK was even darker then the control line which means my LH surge happpend and ill ovulate 6/7. I'm still spotting and it's about to be 4 full days of spotting. Is this normal? Has this happened to Anyone?
