The fertilized egg moves into the uterine cavity and implants in the endometrium 6-7 days after fertilization. Most women have no symptoms at the time of fertilization, but some may experience mild back pain and breast fullness. A small number of women experience vaginal bleeding, mostly light red, which can occur up to 8 days after implantation. Some women also experience frequent urination because the body secretes human chorionic gonadotropin after fertilization, which can stimulate the bladder and cause frequent urination. Since most women do not have symptoms after fertilization, it is recommended that a pregnancy test and ultrasound be performed at the hospital 20 days after ovulation to determine if you are pregnant. If pregnancy is confirmed, it is important to take proper rest and avoid exertion and cold. You should not eat cold, spicy and stimulating food, and eat more fresh fruits and vegetables, especially vitamin and protein-rich food, such as eggs, milk and lean meat, and increase water intake. Pay attention to keep the pubic area hygienic and clean to prevent infection. In addition, sexual intercourse should be forbidden in early pregnancy to avoid miscarriage, and to develop good regular habits, sleep on time and avoid staying up late to facilitate the growth and development of the embryo.
