First response early result are excellent. I got a nice clear positive line at 11dpo. I'm sure I'd have had a feint line a day or two earlier.
Superdrug own brand are equally good. i got a very convincing result on the same day at 11dpo. The internet cheapies showed positive on that day too but the line was very pale and I wouldn't have trusted it as a convincing result.
I don't like the Clearblue non-digi tests because they have blue lines. Pink line tests, especially if they are not the cheap dip strips, are less likely to produce an evaporation line.
I haven't done a CB digi yet. They are the tests of the devil because unless you wait until you know it will be 3+, they know you will be back buying even more of them waiting for the numbers to go up.
No point testing before 11dpo. FR only 60% accurate at 9dpo so if you get a negative you won't trust it, and if you get a positive it will be super faint and you will only end up doing it again!
First morning urine, ie first pee when you get up. In theory it is more concentrated, but you don't need it for testing. I actually got a better result in the afternoon after I didn't go to the toilet for 4 hours and tried not to drink loads during that time.
