What happens during conception and implantation?
Implantation: what happens after the egg is fertilized It takes about 6-12 days for the fertilized egg to travel to the uterus and attach to the uterus in a process known as implantation (1,8). The egg is pushed back towards the uterus by the cilia (1). The egg must attach to the uterus to become a viable pregnancy.

What comes first fertilization or implantation?
Implantation. Once the embryo reaches the blastocyst stage, approximately five to six days after fertilization, it hatches out of its zona pellucida and begins the process of implantation in the uterus. In nature, 50 percent of all fertilized eggs are lost before a woman’s missed menses.
Which side implantation occurs?

Can you be pregnant 3 days after ovulation?
Pregnancy After Ovulation Getting pregnant after ovulation is possible, but is limited to the 12-24 hours after your egg has been released. Cervical mucus helps sperm live up to 5 days in a woman’s body, and it takes around 6 hours for active sperm to reach the fallopian tubes.
Can you feel tired 3 days after conception?
Many women feel tired in early pregnancy. That’s because the pregnant body is working overtime to maintain the pregnancy and develop milk-producing glands in the breasts. Some pregnant women notice this fatigue even as early as one week after conception, making this one of the first noticeable signs of pregnancy.
Can implantation occur in 3 days?
Implantation occurs from 6 to 12 days after fertilization and around a week after ovulation. This puts it near or just before the time of menstruation in most cases. If it has been more than a month since a woman has had sex, she is unlikely to be experiencing implantation bleeding.
