weird things around ovulation

Cd 15 - ewcm
Cd 16 - ewcm
Cd 17 - ewcm mixed with slight spotting
Cd 18 - + opk, slight spotting and ewcm
Cd 19 - + opk and slight spotting and ewcm and twinges all day in right ovary
Cd 20 - creamy cm with spotting
Cd 21 - a little more spotting
Cd 22 - started bleeding medium amount 
Cd 23 - medium to heavy bleeding 
Cd 24 - light bleeding 
I have had absolutely no cramps whatsoever like af usually, but just odd twinges in right ovary like at ovulation all through the bleeding?! 
Has this happened to anyone or do you know why this might be happening?
