I just saw the other posts about testing. If you can wait a bit longer, you will get a more accurate result. I tested when I was 12DPO & got a faint +ve with Assurance Plus. I tested again later that day with Discover Onestep & got a strong result. The other thing you may not know is that you should test first thing in the morning - hormone levels are more concentrated in urine if it's your first pee of the day. (sorry if TMI)
