I am 8 days DPO. So pretty early in the process. I felt 'weird'- bloating, tender chest- so I took an early test. There was a faint line. I took three tests over the course of three days , still faint lines. I have been trying for my second for a while so I am tracking everything closesly. I went in for a blood test and they told me the result is negative. ( Ive also had a few miscarraiges and seen an RE for any issues- NONE)
Why do I have a faint line? This happen to anyone else? Is it just way to early to know.. |

| The diagnostic range for blood tests should capture even the earliest of pregnancies. I think it was a lab error. |

| Buy a different brand of at home test and test again in a couple days. If you don’t get your period, it was likely a lab error. If you don’t get your period, call and schedule your first prenatal appt. |

| How faint is faint and how many minutes did you give it? Most of those tests will give an evaporation line that can appear to be a faint positive if you let it sit for like an hour. If it’s a faint line after just 2 or 3 minutes then that’s usually real. It should get darker day by day. If it doesn’t get darker, and you get your period, then it’s just a hard to read test and I’d get a different brand next month. I had a very faint positive and got blood work the next day- around 10 days post ovulation- and my hcg was about 25. So , super early, but clearly pregnant. “Negative” makes me think hcg was zero? Because after getting methotrexate for an ectopic they tracked my hcg down to zero, and I remmeber getting one reading of 8 near the end . Which makes me think it really does go down to zero on the tests. |

It was faint but visible after five or so minutes. It was the red dye test. I think first response ? |

| Call your RE and ask if it was actually 0 or something under 5 that is considered negative. Did you try different brands and batches of tests? First Response has been having some issues with dye runs, so if they were all from the same box, it could be a faulty test issue. Or if you took the tests a few days (or even a day before) the blood test and it was a very very early chemical, then it could be that HCG dropped so quickly that it was negative by the time you got to the doctor. If that was the case, then it would have been regular progesterone causing your symptoms, since pregnancy hormones would have to be higher to give you symptoms. |

| How many dpo were you when you did the blood test? Have you missed a period? If not just wait a few days and see - if period doesn't come then take another at home test and schedule f/u appt |

Op here. I am 8 days post ovulation but not expecting my period for another ten. It’s crazy early!! The only reason I tested is because I felt “something” going on inside me. Bloating and tender chest. I’ve been pregnant enough time to know how it starts sadly......and this felt close. You never know... |

| Buy a test that says pregnant or not pregnant. |

Oh dear, 8 DPO is progesterone for sure, not pregnancy. Progesterone can mimic early pregnancy symptoms really closely. Even if you had a super early implantation, that’s just not enough time for hormones to build up enough for genuine pregnancy symptoms. |

| My negative blood test that my doctor insisted was just in my head because blood tests are never wrong is now 11. |

Okay but this is 12 years later with an RE. Lab error maybe, but no REs aren’t just wrong about whether you’re pregnant. |

But isn't the blood test the same? I don't think that has changed. |

what about a chemical pregnancy?
Keep testing. keep expectations low. |

Not trying to question your experience, bu unfortunately years at the RE and recurrent pregnancy loss have made me a sort of reluctant expert on these matters. It could be the difference between a qualitative and quantitative test. At the RE, you'll get a beta number that could be counted as negative if it's less than 5. That could be an early chemical or it could be something in your system causing low levels of HCG (which is rare, but possible). Some labs/doctor's offices consider beta results between 6 and 25 to be indeterminate until you get a repeat beta to confirm it's rising, even though a RE would consider that a pregnancy because they need to know if there's implantation starting (relevant for figuring out infertility cause and treatment) and over 5 is high enough that it wouldn't be residual HCG not caused by pregnancy. So it's hard to compare the situations without knowing more details. So TL;DR, yes, blood test is the same, but the lab and/or doctor's interpretation could be different. |
