As per my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> I'm about 10 days until AF. Today I had a ton of extremely white CM. I mean, the most I've ever had in my entire life! Also mixed in was a little bit of pink blood. Not a lot. I felt a couple twinges on Weds-Thurs. but nothing major.
Couple it be implantation?
