Ok, firstly, I'll give a little technical info: The IC's I've used
claim to have a cut off of 10 miu. Why is the word 'claim' italicised? Well, they gave me a negative a 12dpo... and a very faint line 15dpo (click thumbnail to enlarge):
Here's the FRER I dipped in the same first morning urine as the IC at 15dpo. The partline is they have a sensitivity of 25 miu although there is plenty of anecdotal evidence they pick up much lower than that. However, this line is by NO means a squinter (again clicky):
So then I dipped a digi with conception indicator and got a 'pregnant' result. I cannot find published sensitivity of this exact test, but the regular digi's are 50 miu, I believe. That would correspond with the nice line on the FRER. That faint line on the 10 miu IC is looking more and more like they're fibbing about the cut off, right?!

:
ANYWAY! So bearing all that in mind, my progression. I've tested virtually every day! Some, like the second test, are PM (the first was 6am, the second 11pm the following day). The final one is this mornings...and may be a little different looking because it might still be, uh, moist.
