Ovulation Symptoms 1 Week Before Positive OPK

Kyrstan
About one week before I had positive OPKs, I was experiencing ovulation symptoms like cramping and aching breasts. Also, my CM was egg white consistency but I was getting negative OPKs. My husband and I BD'd just to be sure, and then a week later I had three days of positive OPKs with cramping and pink spotting that went away almost as soon as it happened! 
Has anyone else experienced this? When would you say I ovulated?
