06-11-2009 - Stats for testing

My mood while writing this blog: Interested

---

Was just looking around at testing stats and found this thought they were interesting.

Here are percents on BFP when going by dpo:
35% at 10dpo
51% at 11dpo
62% at 12dpo
68% at 13dpo
74% at 14dpo
80% at 15dpo
88% at 16dpo
92% at 17dpo

And from the FF website:

Average Day Past Ovulation (DPO) for the first positive pregnancy test:
13.6 DPO


Average DPO for the first "false" negative test result:
10.3 DPO


Percentage of pregnancy charts with a positive test at 10 DPO:
10%


Percentage of pregnancy charts which show negative results before a positive result:
17%


Average time between the expected period and the first positive pregnancy test:
0.5 days before the expected period.


Percentage of negative test results taken three days or more before the expected period day on non pregnant charts:
40.7%
