Pregnancy tests will catch less than 70% of pregnancies at 4 days before a period. A few things to understand about pregnancy tests. When they say you can test up to 5 days before a missed period, that means 4 days before your period is due. That number is based on an average luteal phase (the time between ovulation and the first day of your period) of 14 days. Which means those tests recommend testing no sooner than 10 days past ovulation.
Usually 14 days or more is best. You might get a positive before then, but it is not very accurate until day 14. I tested at 10 and got negative day 14 got positive. Sieunique, Tests are MOST accurate 5 days or more after your missed period. (They are only ~60% accurate at day 10 after conception--that's before your period. They increase to 97% by day 5 after your period. This is from reading the back of MANY boxes when trying to get pregnant) That's abotu 18-19 days after conception for most women, so yes, if you tested sooner than that you could be pregnant and have gotten a false negatvie.
