I started spotting late yesterday! I went to the restroom and when I wiped I saw what is on the top picture. I didnt have anymore spotting for the rest of the night or any today. I just went to the restroom 10mins ago and saw what's on the bottom picture. It doesn't show up when I wipe but only when I insert a finger and wipe it off. My last AF was Jan 7 2017. Glow says I'm suppose to O tomorrow but I have yet to get a positive OPK. I'm getting really confused and stressed out. What can this possibly mean. Also I had an abundance of CM up until yesterday when the spotting started. Now nothing.
