With my chart, why I think it doesn't look favourable is because I'm due af Tuesday and my temps usually go like this: 11dpo dip, 12dpo dip, 13dpo slight increase, 14dpo dip, followed by af the next day. This would tie in with af being due Tuesday, so I was hoping for an increase today. I know it isn't always a perfect science, but it does seem to be my pattern.
I have a Superdrug left for tomorrow, a few ICs which so far look blank with the exception of super faint lines in the evenings but I think these are what I usually see on them.
I won't be buying any more expensive tests unless af doesn't show.
Oh, and yes you are right, Crazy. Superdrug early is more sensitive, I think FRER is 12.5miu
