Ffs my body is screwed :- I was almost out of opks and have a different patch these are thinner than others but same make, anyway past few days I've used them at same time as others to compare them against, at 1015 I used my last one from batch 1 and was negative and new ones matched almost same shade if not the same, just done a test at 1.15 and fainter than ever? So I used another one and it's the same :s and like hardly any cm now at all,I give up!
