Egg white discharge with pink CD 13

According to Premom I ovulated 4 days ago.

I had sex the day before and the day of ovulation.

Today I had egg white discharge for the first time this cycle but it had pink in it.

Then an hour later it turned to light brown all most tan.

Could this ovulation?

Any girls that experienced something similar to this.

opk and bbt are still not showing I ovulated.
