How reliable are the Superdrug early response tests? I’m 10DPO and have just done one and a boots early response.. the Superdrug one is obviously positive but the boots one has the faintest line ever that might even just be line eyes.. dipped them into the same sample! And I don’t have more tests until my Amazon delivery later! I’ve fully convinced myself this Superdrug one is faulty! And this picture was took within a 10 min time frame!
