Oh Mindy, I know everyone is different, and everyone has different outcomes. But, in my case. This pregnancy and my last, I took a clear blue digi and Frer digi at 14 dpo. They clearly said NOT PREGNANT, but I was still getting very light lines. At 16 dpo It said PREGNANT, and my pregnancy test lines were still light. I was 18 dpo with my last, I bought a 2 pack. The first one said Not Pregnant, 2 hours later Pregnant. I went to the doctors to get it confirmed. He said I was not pregnant, after I told him about all my light lines and the two digis a day before. He did a blood test and confirmed I was indeed pregnant I was 19 dpo the day blood was taken. My dates where confirmed I was as far along as I said by ultrasound. My first 4 children, 3 of my children I test pos at 7 dpo many,many years ago. When the doctors said there was no way a test would show pos before a miss period. With my last 3 pregnancies they are taking 13 dpo and up, to show a faint line. These test now they say are soo sensitive, seem to be crap. I think the test I used 16-12 years ago had the sensitivity of a 100+ for HCG. The funny thing is, my lines where darker at 7 dpo with the old test, then 13 dpo with the new test. Makes me wonder if they are not doing something to make women buy more and more test. They funny thing is I see women with lines all the time ( myself included) who get faint lines, buy new 10 more to see if they get darker and end up not being pregnant. 16 years ago If you had even a shadow you where a 100% pregnant, now its a joke..........But anyways, sorry for the RANT i just hate to see people hurt, and think their dream is gone. I would just trust the blood test, you are pregnant and I am so sorry you have to worry..good luck
