Pregnancy Test Sensitivity Comparison
Choosing a Sensitive Pregnancy Test
In the chart below, the smaller the number in the "hCG Detected" column is, the earlier you can use the pregnancy test. As a general rule, hCG levels, if you are pregnant, are between 5 - 50 mIU a week before your period is due. The hCG levels in your system should double every two to three days.
Detection of pregnancy depends on the sensitivity of the pregnancy test AND how your system is creating the hCG. hCG is created by your uterine lining once the fertilized egg has implanted. Every woman is different and the time it takes for the fertilized egg to implant in your uterine wall can vary. Research show implantation typically occurs 6-12 days after ovulation, with 84% of the pregnancies implanting on days 8-10 after ovulation.
If a negative pregnancy test, it doesn't mean that you are not pregnant. It could be that you ovulated later than you thought (meaning that conception and subsequent hCG production didn't happen as when you expected) or that, for you, implantation took longer than the average. Your period arriving is a sign that you are not pregnant this cycle, as is a negative blood test from your doctor.
