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!
Good luck.
