I was prepared to start my clomid next month and had collected the prescription ready. I always spot for a few days before my period started and that day I noticed a few brown spots as usual before it stopped. That was 10 dpo. Anyway nothing since then and so I tested yesterday 2 days late and got a faint line on a test from the co op. I couldn't quite believe it and went to buy a clear blue today which was negative. I'm a little confused now- the line on the co op was there but faint but then nothing on the clear blue. Don't want to get my hopes up but I am a front line worker so I need to inform work straight away if I'm pregnant. What is the best way to confirm either way?
