I did about 4 HPT's in the days following my missed AF with DD. The first one, mid-afternoon, was faint but positive, when AF was 3 days late (about 15DPO). My 2nd one, with FMU, was barely there at about 18DPO. My third was the same as the first with FMU at 21DPO, my 4th was the same as the first and 3rd, with FMU at 22DPO. THen i gave up because i was torturing myself with the results even though they were meaningless - all my tests were the same brand but i realised there was only so much dye in each stick and depending on how much urea there was (which is what the test line is - it tells you that the tests is working i.e. that you have put wee on it and not cola or whatever) in my pee there just wasn't ENOUGH dye to make a dark 2nd line. ALl the dye left no doubt made the 2nd line, but that wasn't actually realted to how much HCG there was in my urine, if that makes sense. My tests worked with any HCG numbers over 50, but they didn't actually give me a significantly darker line necessarily. I did one more at about 4 months PG and the same thing! A faint positive! So while it could be a sign that there's something going on, it could mean absolutely nothing at all.

Thinking of you hun.
