The follicle is usually discharged within 24 hours after the injection, and there is a higher chance of pregnancy if you have intercourse within 48 hours.
Usually the egg survives for 48 hours after discharge and the sperm can survive for 72 hours after entering the vagina, as long as the sperm and egg meet during this period, conception can take place. If the follicle is mature and cannot be discharged on its own, ovulation stimulating drugs can be used to promote the discharge of the egg. 48 hours of intercourse (sperm into the vagina), the survival of the sperm may meet the egg to form a fertilized egg, the chances of pregnancy are greater.
In addition, pay attention to relaxation and keep a good state of mind, emotional tension is also not conducive to pregnancy. One week after ovulation, you can go to the hospital for blood test for human chorionic gonadotropin or use early pregnancy test paper to test whether you are pregnant after your period is delayed. If you have any discomfort during the period, please go to the hospital in time to avoid adverse consequences.
