How the Pregnancy Test Dates Are Estimated

From a last period and average cycle length, the calculator estimates ovulation 14 days before the expected next period. From a known ovulation date, it counts forward 14 days. The suggested first test date is the expected period date. After a negative result, it shows a later one-to-two-week window rather than claiming an early negative rules pregnancy out.

Home tests detect hCG in urine. Natural variation in ovulation and implantation means some pregnancies are not detectable on the first day of the expected period: in a prospective study, the theoretical maximum sensitivity on that day was 90% and reached 97% one week later even with an extremely sensitive assay. Real test sensitivity, urine concentration, timing, and correct use add more uncertainty. Visitors should follow the instructions for their specific test; irregular cycles make the calendar estimate less reliable.
