What does cervical mucus after ovulation mean?

I had a positive LH surge 6 days ago, and I ovulated 5 days ago. I heard that cervical mucous is eggwhite when fertile but dries up after ovulation. My cervical mucous is not as abundant as last week, but is a little creamy, eggwhite, and stringy still. I have usually noticed that I do dry up after ovulation, but this time I haven't. Could this be a sign of implantation? Thanks!
