Thought af was starting yesterday on cd 17. Spotting 2 day ago. Red blood yesterday. I use a soft cup for af so I put one in yesterday. Mostly ewcm this morning with a tinge of brown. Having cramping like af but mostly on the left side. My opk last night was half as dark as the control line. I tested even though I thought it was af. I think my cervix should be closed if it is af. This morning it is very high, very soft and open. It sort of blended in with the rest of my vagina.
