What are the Signs of Successful Implantation?

Pregnancy is a complex procedure and isn't as simple as you think. Conceiving involves many hormonal processes and stages to result in a healthy pregnancy. Implantation is also one of the stages in pregnancy where the embryo or blastocyst attaches itself to the walls of the uterus.


Implantation triggers your body's reproductive hormones (estrogen, progesterone, and hCG, or human chorionic gonadotropin) to mark the beginning of pregnancy. However, if implantation doesn't happen, your uterine lining will be shed in your normal monthly period.


For couples who have undergone a form of Assisted Reproductive Technology (ART) like, In Vitro Fertilization (IVF), the fertilized egg is created in the laboratory. After the embryo is formed, it is cultured under observation to determine if it has the potential to cause a successful pregnancy.

In the next stage, the embryo is transferred into the uterine cavity, where it is expected to attach itself to the lining of the uterus for further development. Otherwise, one may opt for the Frozen Blastocyst Transfer (FET), which occurs after a period of time depending on factors and the couple's personal decision. For frozen Blastocyst Transfer, preparing your uterus for blastocyst implantation is important.

When Does Implantation happen?


Implantation happens any time between 5-10 days after you ovulate. More precisely, the exact date of implantation can depend on when you ovulated or when conception occurs. The cells start to divide in the embryo, developing into a zygote that attaches itself to the uterine walls.

The zygote then releases a hormone called human chorionic gonadotropin (hCG), also known as the pregnancy hormone, which is used by pregnancy tests to determine pregnancy.

Signs of Successful Implantation

After the implantation, your body may start showing the signs of early pregnancy. However, in some cases, there may not be any sign, but it doesn't conclude that you're not pregnant. Sometimes women experience no signs but are still pregnant in a pregnancy test. Here are the most common sign of implantation:

Cramping

Low to mild cramping may signify early pregnancy as implantation triggers a shift of hormones. It is possible you may experience lower back pain, abdominal tenderness, & cramping during the successful implantation.

Bleeding or Spotting

In a few cases, successful implantation also causes bleeding. Implantation bleeding often gets confused with the regular period. So, to determine if it is successful, you notice that implantation bleeding produces much less blood than your period, and it is more like spotting than an actual flow of blood.

Breast discomfort

The implantation triggers levels of hCG, estrogen, and progesterone. This may cause tenderness of the breasts along with slight swelling and may last for a few days.

Mood Swings

Many women during early pregnancy notice mood swings and changes in food preference due to the alterations in hormonal levels.

Change in Body Temperature

A slight increase in body temperature is common because of the change in progesterone levels. It is seen that body temperature is lower before ovulation and then increases for a period of time before a period starts. Around the time of implantation, you may notice a one-day drop in temperature.

Bloating

Some women also seem to experience bloating as elevated hormones slow their digestive system down. However, this is a common sign in your periods too.

There can be other signs of successful implantation that vary from person to person, such as headaches, nausea, soreness, etc., and even you may notice no sign at all.

Pregnancy is an exciting & nail-biting time, and a tiny change in the body can make you question many things. The best way to ensure you're pregnant is to take an initial pregnancy test at home by measuring your hCG hormone level, or it is even better to talk with a fertility specialist at Crysta IVF.
