EWCM after ovulation???

Has anyone had EWCM after ovulation?? I’m pretty sure I ovulated on July 15, had very mild ovulation cramps and EWCM till the 16th. Today I went to the washroom and had a bunch of EWCM again but just the one time. I also had twinging pinching cramps. Is it possible implantation has already happened? That seems too quick.
