WORD OF CAUTION - having recently experienced an early miscarriage, I sought advice from the Early Pregnancy Assessment Unit and the senior nurse that I spoke to advised against using Clearblue Digital Tests as the they have had many women getting false positives and false negatives on them. EPAU use pink strip tests and so do other departments within the hospital (I work there as a midwife) i.e. gynae wards (For women about to undergo surgical procedures - who are tested to rule out pregnancy)and A&E departments. Despite Digi's being popular because it tells a women she's 'pregnant' it's worth considering information above as EPAU deal with pregnancy testing a day to day basis!
