how long can fertilization takes place if i have sex on safe days
How long does implantation take? Starting from ovulation, fertilization takes place within 24 hours, this is the beginning of conception. After the egg (ovum) is fertilized, it travels down the fallopian tube and enters the uterus about 5 to 7 days later. Once there, it still takes about 1 to 3 days before it implants.
