Clearblue Digital - how accurate

Hi girls, just wondering, how accurate is this text? Am 3 weeks late and got a 'not pregnant' result. Anyone else use this test?

Tbh I found them the most accurate. Maybe try it again in the morning when pregnancy hormones level would be at their highest? If, a week later and you still haven't gotten AF then test again maybe?

Thanks island. We hadnt planned on starting TTC til after the wedding - we get married in aug - but reading stories on here, we would be delighted if we got a BFP. AF was due 1st of the month, usually bang on. must be something external this month.. it says its 99% accurate??

Well I guess there's always that 1% alright! Definately try again in the morning - I would advise to not keep buying them though. Wait another week and if you're still late then maybe test again? I should have had shares in Clearblue with the amount of tests I bought.
