I was totally impatient too. My doctor said that a blood test would show positive 10 days after conception, and I was dying to know so I went in 10 days after my blue line. The test was negative, I cried and cried, wanted to die for awhile, accepted it, and looked forward to the next month. Then two weeks went by � no period. I was frustrated, figured I'd have to take Provera to bring it on or something. I did a home pregnancy test for the hell of it, and lo and behold it was positive! So I jumped the gun. I would recommend that you not take a blood test until you are pretty sure it's 10 days after ovulation. What happened to me was an emotional roller coaster!
I also tested negative on a blood test, approx. 10 days after conception. I still had a hunch that I could be pregnant, even though everyone else tried to convince me that the tests don't fail. It turns out that maternal instict is stronger and I was indeed pregnant. Believe in yourself and your instincts.
My doctor told me that a blood test could test for hcg 3 days after conception.
I went into the doctor's office for a bladder infection. He asked me if there was any possibility I could be pregnant because if so then my presciption would change. I wasn't sure so he tested me anyways. It came back negative. A month later I found out I was 6 weeks pregnant, meaning that I was two weeks pregnant at the time of the test. So they aren't always right.
I got a positive on my home pregnancy test 9 days after ovulation. I went to get a blood test and it was negative. I have since gotten 5 days of consecutive positive results on 3 different brands of home pregnancy tests.
Depending on what test the doctor uses will depend on the sensitivity. A
qualitative test is a basic test ran at most labs and it only gives you a yes or no answer if your pregnant. This test is not as sensitive as most home pregnancy tests are, and it is suggested you wait about a week after your missed period to take it. A
quantitative test measures the exact amount of hCG in your system and that can give you results as early as three days after conception, but most doctors will not run this unless you request it, or in the case of a suspected miscarriage.
My doctor told me that I probably tested too early and that I should wait a week after my missed period. Until then I will continue to test each morning, but in the past 5 days the results have gotten stronger and stronger. I don't think there's really a doubt that I am, cannot imagine getting like 15 false positives on three brands.
