How much earlier can a FRER test pick up pregnancy than a cheap 20mlu test?

ju

So I bought 3 cheap tests which are 20mlu and all negative, which I assumed they would be as I still have 4-6 days left before my period.

Just wondering if it’s more than likely that they are correct and negative, or if I’d get a better response with First Response?

I know I’m testing early but the waiting is just too much! 😩

Is it worth wasting £9ish on First Response yet or waiting?
