Ok, so I had previously taken 6 pregnancy tests and 4 showed a second faint line... the other 2 were digital and said NO. Then I went to see my OB today and they did a pregnancy test and the lab tech said she seen a very faint line but then it went away. So, they did a blood and I can call back tomorrow for the results. The lab tech said it's possible I'm too early and so it isn't picking it up on the urine test. Also, they said it could be that I still have some HCG floating around in me. They also said if the number is a 5 or higher on the blood test then I am pregnant. What does all this mean and has any of this ever happened to anyone and what was the results? Our daughter will be 2 month's Monday the 25th.
