ff chart question

[KElwanger]

What does an dashed line mean on my ff chart? I'm not charting very well I don't think. I haven't been doing it at the same time every morning and then when I added in today's it did the dashed line so now I'm thinking it's just all screwed up...

As far as I know dashed line means FF is not 100% sure on your O day. It can depend on timing of temping, CM pattern, OPK results. Normally if there is a dashed line FF explains somewhere in the page why it is so.
