CNN reported that in 2014 close to 1.5 percent of the 4 million babies born that year were the result of in-vitro fertilization or intrauterine insemination, otherwise known as IVF and IUI. In fact, studies show that more women each year are using one of these methods to conceive and have children. As popular as these conception methods are today, women still may wonder just when implantation will occur after they undergo these procedures. These procedures are designed to mimic as much as possible the natural conception process in women who do not have issues with fertility or conceiving.

After a woman undergoes and finishes her IVF or IUI procedure, she can expect the fertilized blastocyst to implant itself in her uterus in about five days, if the procedure was indeed successful. These five days mirror the time it takes a fertilized egg after natural conception to travel from a woman’s fallopian tubes and implant itself in her uterus. As with any pregnancy, implantation depends on a number of different factors, notwithstanding the woman’s overall health and the condition of her uterus. A woman who has serious gynecological issues like endometriosis or anemia may find it more difficult to conceive even with IVF and IUI methods.

If the implantation is successful, the woman who underwent one of these methods can expect to take a pregnancy test and receive a positive result about two to three weeks afterward. This time frame mimics that of any other pregnancy; a woman who conceived through natural means likewise must wait about two to three weeks after conception to test and receive a positive result. During the weeks leading up to being able to test, it is important for the IVF or IUI patient to avoid stress, heavy lifting, and eating or drinking foods and beverages that could induce a miscarriage.

How Early Can Implantation Occur?

When a woman conceives naturally, she typically can base when implantation occurred based on her menstrual cycle. If she has a typical 28-day cycle, for example, she probably ovulates between the 11th and 16th day of each month. If she had unprotected sex and conceived on any of those days, she can typically expect implantation to take place anywhere from six to 11 days after conception. This amount of time allows the fertilized egg to travel from its place in the fallopian tubes to the uterus. Scientists speculate that the average amount of time between fertilization and implantation stands at around nine days. However, each woman can vary depending on her cycle.

If a woman goes through artificial means to conceive, such as IVF, she may be told to expect implantation about five days after undergoing the procedure. Despite implantation taking place, a miscarriage can still occur. In fact, women who conceive naturally may not even know that they are pregnant, but assume that they are simply late on getting their periods. With IVF, however, women usually know that they are pregnant, yet still at risk for a miscarriage. As such, some women have to go through an in-vitro fertilization procedure several times to become pregnant successfully.




When women want to reduce their chances of miscarrying, regardless of what conception method they use, they can undertake some basic steps to ensure their health and that of any pregnancy that may occur as a result of their efforts. First, doctors may tell women to stop drinking caffeinated beverages, as well as alcohol. Caffeine and alcohol both increase the chances of a miscarriage. Second, women should start taking prenatal vitamins as soon as they decide to try to become pregnant. Prenatal vitamins contain nutrients like iron and folate that help foster healthy pregnancies. Third, women are usually warned against stress and physical exertion. They must allow their bodies and minds to rest so that they will not inadvertently reject a pregnancy, nor cause their blood pressure to rise and cause a miscarriage.

When Does Implantation Occur After Ovulation?

Despite ovulation taking place around the midpoint of a woman’s menstrual cycle, her pregnancy will not implant itself for at least another week, if not a few days longer. During the time between ovulation and conception to implantation, the fertilized egg undergoes a series of rapid and overwhelmingly noticeable changes until it reaches a point where it can implant itself into the uterine lining. It is at the point of implantation that many women consider themselves to be pregnant. In fact, just a few days after implantation takes place, a woman could take an early detection pregnancy test and possibly receive a positive result.

Once the pregnancy implants itself and begins to grow, a woman’s body will undergo rapid changes to prepare her for being pregnant and delivering a baby. By the time she expects her period to start, she may already be experiencing morning sickness and frequent urination, two signs of early pregnancy. She also may develop dark lines on her breasts and abdomen. As the baby grows in her uterus, a woman may also notice that her skin becomes smoother and her hair thicker. These changes occur because of the hormones produced by her uterus as it protects her unborn baby.

After 12 to 15 weeks after implantation, most women begin to notice their abdomens swelling and becoming rounder. This rounding takes place to accommodate the growing baby and to give it plenty of room to develop. Of course, a woman’s abdomen will continue to grow until the day that she delivers. For most women, a normal pregnancy, whether conceived naturally or by IVF or IUI, lasts around 40 weeks. The countdown does not begin from the time the fertilized egg implants itself in the uterine wall, however. The first week of the pregnancy starts two weeks before a woman even ovulates and conceives. Delivery in a successful pregnancy takes places between 37 to 38 weeks after a fertilized egg implants itself into the uterine wall and begins to develop into a baby.
