How long can implantation take

Implantation itself usually occurs between six to 10 days after the egg is fertilized.

In the case of in vitro fertilization (IVF), the fertilized eggs or human blastocysts normally hatch out of their shell and start to implant about 1 or 2 days after the 5th day of the IVF blastocyst transfer. This means the implantation takes place about 7 to 8 days after fertilization of the egg.

At 4 weeks, the blastocyst has made a 6-day trip from the fallopian tubes to the womb. Here, it begins to burrow or implant into the wall of the uterus.

Implantation that occurs on the late end of the spectrum is known as late implantation. The spot where the embryo attaches itself inside of the endometrium can disrupt some blood vessels, which may cause some light bleeding anywhere from five to 10 days after conception, but before your period would typically occur.

In a natural situation (not IVF), the blastocyst should hatch and implant at the same time – about 6 to 10 days after ovulation.

After implantation, mucus tends to be thick, gummy, and clear in color. Some women experience implantation bleeding, or spotting. This can occur 6 to 12 days following conception.

Think lots of fresh fruits, vegetables, good quality proteins, nuts and seeds, healthy fats and whole grains. The key here is blood sugar control to support implantation and early embryo development, so limit the junk and focus on real, nutrient-dense food.

Timing of Implantation

After conception, the process of becoming enceinte still takes several days, because the fertilized egg (now called a blastocyst) has only just begun its long journey. The blastocyst has to travel from the fallopian tube into the uterus for implantation to take place.

BANANAS: Rich in potassium and vitamin B6, banana aids in improving fertility. It does so by improving sperm and egg quality and regulating reproductive hormones.

The causes of implantation failure are diverse and especially due to different maternal factors as uterine abnormalities, hormonal or metabolic disorders, infections, immunological factors, thrombophilias as well as other less common ones.

Seminal fluid factors modulate the female immune response at conception to facilitate embryo implantation and reproductive success.

Symptoms of unsuccessful implantation

Implantation usually causes changes in the tendency to smell, increased sensitivity of breasts, and slight abdominal cramping. If these do not have any existence even after a couple of weeks, post-IVF, it might be an indicative of a failure.

Plan B works like other birth control pills to prevent pregnancy. Plan B acts primarily by stopping the release of an egg from the ovary (ovulation). It may prevent the union of sperm and egg (fertilization). If fertilization does occur, Plan B may prevent a fertilized egg from attaching to the womb (implantation).

Stress can prevent the implantation of a fertilized egg.

Stress can affect hormones that reduce blood flow to the uterus and endometrial lining making it less receptive to implantation.
