Question

4 positive hpt, positive clear blue digital but negative blood test? ??

Since the 17th of may I have been getting positive hpts. I have had some symptoms ie. Sore breasts, tires and back ache at night. I did a ckear blue digital this morning with fmu and got "pregnant 1 - 2". I took that as a definite. Went to do bloods today to just confirm what the cbd had said but got NEGATIVE. Is it possible that the blood test is incorrect, is it possible that I am still pregnant? The first day of my last period was 21 April 2014. Im so confused and it is extremely frustrating to not have that definite positive. I have an appointment for 17 June 2014 but seems so far away. Please can you comment and better yet let me know if you experienced the same thing.

It depends on which type of blood test you had. For my first pregnancy, something similiar happened. I had several BFPs on numerous brands including two digitals, but the blood work was negative (my DD is almost 2 now so I was most definitely pregnant). You need to find out if it was qualitative or quantitative blood test. Qualitative is just a 'yes' or "no' test based on a predetermined level (i.e. if you had a 24 if it's negative but 25 or above is positive...some set the limit at 50). A quantitative measures the actual level of hcg in your blood. That's the test you want. I was freaking out too, and that doctor wasn't willing to retest me. I'm like, I have to be pregnant we've been TTC for over a year this doesn't make sense (and I have high blood pressure so I couldn't wait around for my doctor to change her mind). I found a new doctor, was retested and sure enough my hcg levels were over 1000. If AF doesn't show, request a new test in a few days. GL!

Hi Steph35. Thank you very much for your response.

It was a qualitative blood test.

I am still feeling "pregnant" (I know too well that it can all be in my head but this time its definitely different and have a whole lot of hpts to prove it).
It's all just extremely frustrating as all I want is a clear yes or no. I hate the "not knowing".
I have an appointment on the 17th (which feels years away). If I AF does not show by next week I will try go get another blood test.
I truly hope this is it.
You have definitely given me a bit of hope :-)

Thanks.

Yay! !! Went today for another blood test and its positive. Just must have been too early the first time I went. That means a clear blue digital picked it up before the blood test did. Was very lucky, got to see how the whole process works while I was there. They spin the blood then only use the serum that is seperated on top from the spinning to put on a test strip that looks exactly like a urine hpt, with the control and test line. So very easily can get a false positive. Hope this info is useful. ..was to me. Gl xx

I know i am a bit late. Congratulations on you BFPS. I am going through something similar and the wait is just... killing me. I have to stay calm infront of my spouse and best friend who knows this happened. I feel sad to get the blood test negative as i definitely saw .. WE saw a faint line on both HPTS taken 10dpo and 11dpo.

May i ask when you did your first blood test how many dpo you were at?
