This is my first month charting and my chart is as clear as mud to me. Based on my symptoms (fertile CM, ovulation pain, spotting) I think I may have ovulated CD 15 or 16. My chart isn't showing a clear spike though to support that idea. Also, I had CM streaked with brown yesterday which would be around 10 DPO if I ovulated then. I'm trying hard to not drive myself crazy but would like to figure out if/when I ovulated. Can anyone else shed some light on this? Thanks!
