I would say they are positive, but so so faint the company would say they aren't. My friend got a positive 4 days after missed period and seriously the line was almost as dark as the control line.
The tests are only guaranteed positive from first day of missed period but keep testing your first morning urine, I found the cheapies off ebay were great.
The difficulty with tests that are 10miu (early detection tests) is that they more often show that light second line, the 20 or 30 miu ones are more trustworthy.
to you temp? Can you post your chart?
I totally know how you feel hon, I have been there last few months, testing like mad, analysing each symptom, and I did it with my ds2 as well. So I feel exactly the same way and know how heartbreaking/stressful and it can be!
