I have had positives at 8/9 DPO and they have been as feint as yours is, the fact it came up at around 10 minutes *could* be an 'evap' or it could just be low levels of HCG (which is not abnormal) I would test again tomorrow or later of you like with the second one (even if its dodge) as it will give you an idea then like pp said get some cheapie tests, I buy the two for £1 ones which are usually more sensitive (starting at 10mui) then once i get a clear pos i buy a proper test
Its a sunmark brand. It was on sale for 2 bucks at the store I happened to be at so I bought them. I wasnt planning on buying them but saw them as I walked out the door. They are NOT expired so I got them.
