How long does it take for a fertilized egg to implant?

Under normal circumstances, the fertilized egg implants about one week after fertilization. The details are as follows:

A fertilized egg is a reproductive cell formed by the union of a female's ovum and a male's sperm. After fertilization, it may take about three days for the fertilized egg to travel into the uterine cavity, and implantation typically begins around seven days later. Implantation usually occurs on the anterior or posterior wall at the upper part of the uterus. After implantation, the fertilized egg starts growing and developing on the endometrium, eventually forming an embryo. Usually, about three days after implantation, women can detect pregnancy using a home pregnancy test. After becoming pregnant, women may experience early pregnancy symptoms such as nausea, vomiting, and excessive sleepiness, which are normal. It is recommended that pregnant women avoid overexertion and staying up late, get adequate rest, and consume light, nutritious foods such as milk and eggs.

Because a woman's body is relatively vulnerable during early pregnancy and miscarriage may occur more easily, pregnant women should avoid heavy physical labor and exposure to toxic or harmful substances.
