Hi hun, i had a book error on a clesr blue digi. On reading the leaflet it said that i had held the test in my urine for too long (i agree with this i didnt read the instructions which said 20 secs!) Your ebay cheapies are definately a BFP and im sure your digi will be. You can do that this evening it will give you a proper reading. Read the instructions again and hold the test directly diagonal into a cup of urine for the amount of seconds it says and no longer and it should be fine. Good luck, not that you need it!!! Congrats!!!
