If you can have intercourse within 30 hours after ovulation, the probability of pregnancy is still relatively high. If you can arrange intercourse in time after the follicle rupture, the sperm can pass through the fallopian tube and combine with the egg to form a fertilized egg in the fallopian tube, then you can get pregnant. If you have intercourse two days after the follicle rupture, the expelled egg will have died and the sperm will not be able to unite with the egg to form a fertilized egg, so it is impossible to get pregnant. In clinical practice, follicle development is monitored by ultrasound and needs to be monitored once a day. If a ruptured follicle is detected, intercourse needs to be arranged in time to make pregnancy easier.
