Mel - I'd go out and get another brand of test. I got my BFP at 16DPO with Pregnosis which you can get from the chemist. They can test HCG as low as 25. Mine was faint but it was definite. My understanding is that evap lines usually show after the recommended waiting time, which is why a postive shouldn't be read after 10 minutes or so. If you are seeing a second line within 10 minutes I would take that as positive. Maybe the cheapie internet tests aren't as sensitive, so go out and get yourself a more sensitive test. Please! I'm that this is it for you.
