urine hormone testing
When are the hormone levels high enough for a pregnancy to be detected through a blood test?

I am wondering about women who tested negative and then later the hormones finally became high enough to be detected. I am 3 1/2 weeks late, all urine tests are coming back negative, but I am having a lot of symptoms, and I am wondering how long I should wait before I request a blood test. I am 32 and have never been more than 2 days late.

If you are 3 1/2 weeks late, then a blood pregnancy test should show something IF you are pregnant. The level is not detectable in blood until 8 to 10 days after ovulation, depending on when implantation took place as well as the specific test assay.
