How Long After Conception Is Implantation (And Why)?

Exact Answer: 5 to 6 Days

Conception refers to the process where the sperm travels to the egg through the vagina and into the fallopian tube to fertilize it.

Conception occurs when the woman is ovulating, which is usually in the middle of the menstrual cycle period. Ovulation can be tracked by various methods to plan pregnancy.

During ovulation, the egg is released by the ovaries and travels to the fallopian tube where it bond with the sperm and the egg would be fertilized. Otherwise, if it is not fertilized, it would be released during the period out of the body.

Conception depends, both, on the woman’s ovulation cycle and the man’s sperm quality.

How Long After Conception Is Implantation?

There are various steps or processes involved in pregnancy. The first would be the transportation of sperm into the fallopian tube along with the release of the egg into the same place where it would get fertilized. Then the fertilized egg would develop into an embryo and finally, be implanted in the uterus where it would grow into a baby.

The process depends mainly upon two things – the quality and health of the man’s sperm and the ovulation cycle of the woman. The sperm must be strong enough to travel through the vagina and into the fallopian tube. The woman’s ovulation cycle would determine the release of the egg after which it would be fertilized by the sperm, as the egg can only be fertilized up to about 24 hours after the ovulation.

After about 5 to 6 days of the fertilization taking place, the fertilized egg or the embryo reaches the uterus and begins the implantation. Implantation occurs when the fertilized egg or the embryo attaches itself, or “implants itself, to the lining of the uterus which is ready for the egg. If the fertilized egg does not reach the uterus, the lining automatically sheds itself resulting in periods or menstruation.

The conception would occur if the person has had unprotected sex anytime during ovulation as at that time, the ovary has released the egg which is ready to be fertilized. Fertilization of the gg through the sperm is very random and has no definite pattern or time to be tracked.

SexRequirement
FemaleThe ovulation cycle should be timed with the pregnancy planning.
MaleThe sperm should be healthy and strong enough to travel to the fallopian tube.

Why Implantation Occurs 5 To 6 Days After Conception?

Conception is the period wherein the egg is fertilized by the sperm and begins to grow into an embryo. The timeline of the sperm and egg meeting is very random and cannot be tracked to a definite pattern or time limit.

Even after the sperm has fertilized the egg, implantation takes up about 5 to 6 days to occur as the egg would just start to grow into an embryo.

The embryo, or blastocyst, needs to travel from the fallopian tube to the uterus where the lining of the uterus is thick for the fertilized egg to implant itself upon. If the egg is not fertilized, the uterus lining would shed itself resulting in what is known as menstruation.

The embryo travels to the uterus and upon entering, is implanted on the lining after which are the cells known as “trophoblast” direct the blood to the embryo.

Implantation can also cause bleeding, which a lot of women go through, but implantation is a sign that the growth of the pregnancy has started.

Implantation causes the body to release the pregnancy hormone which is called “human chorionic gonadotropin.” The pregnancy tests, whether it be urine tests or blood tests, search for the pregnancy hormone within the sample and track the pregnancy through it.

Hence, a positive result on any of the pregnancy tests would mean the implantation has already taken place which is why the body is releasing the hormone. The pregnancy hormone does not gets produced in the body before the implantation, even if the egg is fertilized, which is why the test could turn negative if it gets done before the implantation has occurred.  

Conclusion

Implantation refers to the process where the fertilized egg, or embryo, travels to the uterus and implants itself to the lining where it grows to the whole length of the pregnancy.

Implantation usually occurs after 5 to 6 days of conception, which is the fertilization of the egg with the sperm. The body releases the pregnancy hormone after the implantation occurs, and hence, the pregnancy tests track the hormone which means the positive test would determine that the implantation has already taken place. The test would not turn positive if the implantation has not occurred but the conception has, which could create confusion.
