On Day 16 of my cycle I noticed some reddish pink cervical fluid after a bm. There were two good sized pieces of it and it was pretty thick. I assumed this was just fertile eggwhite cf and that I would be ovulating soon. After day 16 I didn't see anymore of it. Now it is day 21 and I have yet to ovulate so I am curious what that stuff was. I remember seeing it once before many years ago before I was charting. I was just wondering if anyone else had this kind of experience and knew what it was. I've read natural birth control books, but they've never mentioned this type of cf.
