You can tell if you are pregnant very early, sometimes as soon as 6 days before your missed period by using ultra early pregnancy tests which detect the pregnancy hormone human chorionic gonadotropin (hCG) in urine. The fertilized egg implants in the uterine wall about 7 to 9 days after ovulation, and the body starts producing hCG from then, which pregnancy tests detect. Some women notice early signs like implantation bleeding (light spotting), breast changes, tiredness, and nausea about a week or two after conception, but symptoms vary greatly among individuals. A missed period is often the earliest and most reliable sign if you have regular cycles. Other early symptoms may include breast tenderness, fatigue, frequent urination, mood changes, and food cravings or aversions that can appear before or around the time of a missed period. However, to be sure, taking a pregnancy test after a missed period or as early as 6 days before with sensitive tests is the best way to confirm pregnancy.
In summary, pregnancy can sometimes be detected by a test as early as about 6 to 8 days after ovulation, with some early physical symptoms possibly starting as early as a week after fertilization. However, accuracy improves after a missed period.
