Sperm from the first two days of menstruation usually cannot be fertilized after menstruation because the sperm does not survive as long.
In order to conceive, a woman must ovulate, and women who have regular periods usually ovulate about 14 days before the next menstrual period, and premenstrual sperm won’t survive to that time, so they can’t conceive.
Women of childbearing age usually discharge a mature egg from their ovaries every month. After the egg is discharged, it is picked up by the umbrella of the fallopian tube and transported to the juxtaposition of the fallopian tube, and if it encounters a sperm, fertilization may be completed.
The fertilized egg continues to develop in the fallopian tube and gradually moves towards the uterine cavity, reaching the uterine cavity about 7-8 days after fertilization and implanting, gradually developing into a mature fetus.
Women who have intercourse two days before menstruation are advised to go to a regular hospital, consult with a professional doctor, cooperate with the doctor to complete the relevant examinations, and deal with it positively.
