It did. Ive used them before. Personal remcommendation though: use Superdrugs own brang, they dectect from 4 days before ur due, and they measure 10MG up, making them one of the most sensative on the market. PLUS AT £4.70 for a twin pack they are loads cheaper, and there on special too at the mo.
Yes i thought First response was one of the earliest at 5 or 6 days before (in about 56%, percentage went up nearer AF). I had a nice BFP 2 days before AF. Maybe they've changed it or can't maintain their claims any more?
