Got this from fertilityfriend.com... Thought masybe a lot of us (especially me!) should take this into consideration. From now on, Im definitely going to hold off on testing. This shows how rare positive results come before 10 dpo...
Method:
We considered a batch of the most recent charts analyzed on the FertilityFriend.com web site. We considered 93,184 recent charts for which the woman's averages from past cycles were available (most notably the average luteal phase length). For each chart considered we took note of the ovulation day, the first positive pregnancy test, the first negative pregnancy test and the average luteal phase length. From the ovulation day and the average luteal phase length we were able to calculate the day of the expected menstrual period. This latter parameter is extremely important to understand the results.
Results:
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%
