For a pregnant woman, it takes about 6-7 days for conception to take place. In normal female patients, the follicle grows and develops to maturity during the ovulation period, thus releasing an egg. The umbilical end of the fallopian tube will incorporate the egg released by the mature follicle into the fallopian tube, and when both spouses have intercourse during this time, the sperm will enter the uterine cavity from the vagina, and then enter the fallopian tube, where it combines with the egg in the juxta-peritoneal part of the fallopian tube to form a fertilized egg. The fertilized egg travels in the fallopian tube and enters the uterine cavity, which takes about 1 week, and in most patients, the fertilized egg enters the uterine cavity in about 6-7 days for implantation, and the fertilized egg grows and develops in the uterine cavity and gradually becomes an embryo, which is the whole process of conception. It is recommended that patients need to pay attention to the maintenance of the body during this period, pay attention to the diet rich in nutrients, appropriate supplement folic acid, and pay attention to the regularity of work and rest in life.
