Hi,
Took a clearblue ultra early test yesterday and looked BFN within the time frame. Binned it and took another one this morning with fmu. Kept thinking something was catching my eye on the second test but i think am just hopeful and it is BFN again. Went to throw it out, saw yesterdays in the bin and it definitely has a line that looks blue not grey. Faint but there.
Obviously i KNOW that it is invalid outside the time frame but can anyone explain why this happens? Also (a different question) are frer tests actually more sensitive than these? It is still 3 days until my period is due and trying to decide whether it is worth spending money on a frer.
