Light pink cm-help!

I posted this earlier but it has disappeared on me! I'm on cd7 my second week off bc. I had a quick withdrawal bleed over the weekend, but here I am a few days later and having light pink cm? I took an opk and it was negative and glow doesn't have me ov for another week, any ideas what it might be? Thank you for your advice, I'm an anxious TTC mess!
