The egg will reach the fallopian tube in about ten minutes after the follicle ruptures. Under normal circumstances, a woman has only one egg a month. After the follicle ruptures, the egg is discharged and the umbilical end of the fallopian tube transports the egg to the fallopian tube where it is waiting to unite with sperm. If it meets sperm within 12-24 hours, a fertilized egg is formed and then transported by the fallopian tube to the uterine cavity for implantation. If a woman wants to get pregnant, it is best to have intercourse within 12-24 hours after the ovulation, when it is extremely easy to get pregnant. If a woman has blocked fallopian tubes, it is easy to form an ectopic pregnancy, and women should do all the tests before getting pregnant to avoid ectopic pregnancy. If a woman is not pregnant, avoid intercourse during ovulation or take effective contraceptive measures.
