How soon after O does EWCM go away?

Hey ladies...I check my cm every day at the same time a day with my cervical position. I feel like it's all over the place. I only notice EWCM during my fertile window but some days it changes to watery or slightly creamier. I ovulated yesterday or the day before and noticed that my cervix has come down. But today there was more EWCM than there was yesterday. What could this mean? Do you guys still get EWCM right after ovulation?
