Lol they have different types of charts on Fertility Friend but unfortunately I haven't come across a lochness chart.
I actually don't think I have seen a chart like this you know. It kind of looks like the dips are where you have possibly had oestrogen surges, since I think we have two during our luteal phase. I know the first surge is quite soon into your lp, but I can't remember when the next surge is meant to be.
I see it's dipped today, but keeping fingers crossed for you af stays away
