So today FF and glow have both determined my coverline. This was my first month consistently charting so this is a first for me. The problem is glow and FF have both chosen a different coverline (I know glows isn't confimed solid yet). Both have determined ovulation the same day and in sync with when I think I ovulated as well. I'm confused by the way my chart looks where most of temps are above the coverline on both pre ovulation. Has anyone had this happen?
