A woman of childbearing age who has never had sex before is called a virgin. When a virgin happens to be in ovulation when she has her 1st sexual intercourse, it is possible to get pregnant after intercourse. Although a virgin, as long as she has a normal menstrual cycle and her internal reproductive organs: vagina, uterus, fallopian tubes and ovaries are normally developed and open, then when she has intercourse on the day of ovulation and a few days before and after, sperm will pass through the uterine cavity to the fallopian tubes to unite with the egg and develop into a fertilized egg, which will be transplanted into the uterine cavity and continue to grow and develop in the bed, so a virgin can also get pregnant. If a virgin has sex just after her period or when she is about to have her period, pregnancy will not occur during this period because ovulation does not occur in the ovaries. The factors that determine whether or not a virgin can become pregnant depend mainly on the normal development of the female internal reproductive organs and the normal functioning of the ovaries for reproduction and endocrine function. In summary, if a virgin is fully developed, is of childbearing age, is healthy, and has no factors of infertility, it is possible to become pregnant when having intercourse on the day of ovulation and the days before and after.
