Women who have intercourse when they are not ovulating will still have the possibility of getting pregnant, only that the likelihood of such a pregnancy is relatively small, because the male sperm can survive for 72 hours in the female and the female egg can survive for 48 hours, so even if you do not have intercourse at the time of ovulation, then it is possible to cause pregnancy. Some women have irregular menstrual cycles, and the follicles are very much affected by the outside world. Under extreme excitement, the follicles may grow quickly and combine with the sperm to form a fertilized egg, so if you don’t want to have a baby, it’s best to use a condom or IUD every time you have sex. The fact that a woman is not ovulating does not mean that she is not ovulating, and there are also hormonal reasons that can cause early or delayed ovulation, so strictly speaking, there is really no absolute safe period for women. Especially women with irregular menstrual cycles, ovulation is no regularity, so it is not possible to project through artificial methods. Moreover, there are many factors affecting ovulation, such as sexual stimulation, environmental changes, psychological factors and so on, there may be a change in the time of ovulation. The above is to show that not in the ovulation period coitus will still have the possibility of pregnancy, only the chances are relatively low, but not completely excluded. Therefore, women should know how to protect themselves, every time you have sex it is best to use a condom.
