Hi LittleSilver - Well, if it helps I tested CD30 with dd and it was negative, CD34 was a nice strong positive. I don't really know when I ov, though, so don't know how many days po that was, but I reckon you should wait till the end of the week and test again.
I am starting to think I might ov late, though. I don't really do temping and I've never been very consistent using ov sticks, but I seem to remember it being around day 16 that I got a smiley face (or it may even have been day 18) with a Clearblue ov test before I fell pg with dd.
I'm really suspecting a chemical pg, though. I had a negative Boots test this morning, so basically the only tests that have shown positive have been the FR ones. I think they are the most sensitive, though, like you say, LS. But they should be getting darker, shouldn't they? And the one I did yesterday was just as faint as the one on Monday.
So, I have one FR test left, which I'm going to use on Sunday (CD37), if I can hold out that long and if AF hasn't arrived.
Bicnod - I know, I can't believe I'm so broody when dd is only a year old. I think it's because she's been such a good sleeper since six months that I've forgotten the no-sleep hell of the first few months . What's your excuse?
