My first bfp was on an Internet cheapy but they are so vague! Very fuzzy, could hardly believe it. I bought a First Response Early response twin pack - really clear line came up instantly. I think pink due or purple (like the Superdrug ones) are better. Don't get the Boots one's with the + symbol, I got two false positives on those.
Ps I only don't recommend Superdrug because it's a pain to get to from here!
