Ewcm after ovulation???? What does this mean?

Nikkidaisy
Fertility friend confirmed that I ovulated on CD16.. I am now 6dpo and noticed ewcm today. I rarely ever get ewcm so this is weird for me. I have heard it could be a sign of impending implantation due to an estrogen rise thickening the lining of the uterus but I also read it could be nothing. 
Anyone else ever have this happen?
