Introduction
Whether implantation has been successful can be determined approximately one week after intercourse using a pregnancy test strip. If the test yields a positive result for human chorionic gonadotropin (hCG), this indicates that the woman has successfully conceived and that the fertilized egg has successfully implanted and begun developing in the uterus. At the time of successful implantation, a woman’s basal body temperature may experience a slight drop.
Implantation refers to the process whereby the fertilized egg—formed after the union of sperm and egg—attaches itself to the uterine lining (endometrium). This typically occurs 9–11 days after ovulation in women. To determine whether implantation has successfully occurred, a pregnancy test strip can be used approximately one week after intercourse. A positive human chorionic gonadotropin (hCG) test result indicates successful conception and that the fertilized egg has implanted and begun developing within the uterus.
Additionally, a slight drop in basal body temperature often occurs at the time of successful implantation; this phenomenon is known as “implantation dip” and is one of the most noticeable early signs of successful implantation. Following ovulation, a woman’s basal body temperature remains elevated for about 12–16 days. If implantation occurs, her temperature may briefly decline—typically on the day following ovulation—and then rise again the next day. This transient temperature drop—the “implantation dip”—suggests successful pregnancy. Women who have missed their menstrual period for two weeks or longer should consult a healthcare provider for confirmation of pregnancy.
