It's 14 days since smiley OPK, and I am on cd 24 of a 28 day cycle. POAS BFN this morning. Is this likely to be accurate? No symptoms, but tested as its best friend's hen do this evening- needed to know either way! But also curious as to how accurate the result is this early? Is it early? Used a superdrug test. Thankyou for any advice! X
