Hi hotpink I used the superdrug early response test a few weeks ago and got a line. Didn't believe it to begin with as I was only about 8dpo! Just something about it that didn't look/feel right to me. Waited it out another week and done IC when they came in post (bfn) af turned up bang on time so it defo wasn't right! I believe it was an eBay/dud test!
But saying that, if you've had a bfp then don't count yourself out, it could be right !! Try another brand? Good luck X
