Our confidential, lab quality pregnancy tests are 99 percent accurate. A pregnancy can be detected as early as seven to 10 days after conception, although, in some cases, pregnancy testing may not be accurate until 30 days after the first day of the last menstrual period. Common pregnancy symptoms include a missed period, nausea or vomiting, frequent urination, weight gain or loss, swollen or tender breasts and fatigue. The presence of any or all of these symptoms does not necessarily mean that you are pregnant, and you may be pregnant having few or even none of these symptoms. Therefore, confirming a pregnancy through the most accurate means is important.
