ThridTimeLucky - I did the same thing today, resisted a test in the morning but by lunch time I had folded! BFN of course, almost impossible to get a BFP so early I just couldn't help myself with 40 HPT's calling me! I got my current HPT's from Ebay, they are 10 miU which is the most sensitive I'v come across so far. They are also really cheap 30cents each . Hope we both have better luck when testing next week, goodluck.
ETA : The ones I have are Pregnow brand.
