Intrauterine Pregnancy – Everything You Need to Know

During the early stages of pregnancy, doctors will perform a blood test to confirm the conception. An ultrasound follows after the positive blood test report. The presence of a gestational sac and a fetal pole inside the uterus (intrauterine) further confirms that your pregnancy is in the right place.

The Journey of Fertilization to Implantation

From conception, a baby goes through various stages of development, from a fertilized egg into an embryo and then into a baby. The journey from fertilization to implantation is not only exciting but also critical. A woman’s body undergoes ovulation every month after the end of the menstrual cycle. This period is also known as the most fertile window of a woman’s body. During ovulation, you can find that the mucus in the cervix is more elastic to allow the flow of sperm into the uterus.

1. Fertilization

When sperm gets into the cervix, the elasticity of the mucus allows it to swim through and enter the uterus for fertilization. It moves through the fallopian tube to meet the matured ovum or egg. Among millions of sperm, the matured egg released from the ovaries allows only one healthy sperm for the process of fertilization. The fertilized egg is known as Zygote, which further moves into the fallopian tube and enters the uterus. If fertilization does not happen, the egg alone moves along the fallopian tube into the uterus and passes through the next menstrual cycle.

2. Implantation

It takes approximately three to five days for the Zygote to get into the uterus. The fertilized egg begins to multiply into several cells within 24 hours until it reaches the uterus. When the fertilized egg attaches itself to the uterine lining, implantation occurs. At the time of implantation, many women notice slight bleeding or spotting – also known as implantation bleeding. Once the fertilized egg successfully implants in the uterus, the lining becomes thicker, and mucus seals the cervix. After the successful implantation, your body begins to secrete a pregnancy hormone called hCG which can be detectable through blood and urine pregnancy tests.

Confirming an Intrauterine Pregnancy

Have you missed your period? Or did you have a light spotting instead of a period? Do you think you might be pregnant? Then, here is how you can confirm your intrauterine pregnancy.

After you get to see the two pink lines on your home pregnancy test, it is important to let your doctor know about the conception. An hCG blood test will be carried out to confirm your pregnancy officially. 

Along with the blood test, an Ultrasound scan is also required to confirm the exact location or site of the pregnancy. It is possible to identify the presence of a gestational sac within four to five weeks of conception.

Sometimes, the site of the pregnancy will not be precise, which calls for further investigations and tests to be conducted. An early confirmation of the pregnancy site helps you avoid unnecessary complications that an ectopic pregnancy can cause. 

Stages of Intrauterine Pregnancy

There are three primary stages in intrauterine pregnancy – Germinal Stage, Embryonic Stage, and Fetal Stage. Let us discuss more about each of the stages.

1. Germinal Stage

Germinal Stage begins at the time of conception and continues until the sperm meets the egg, fertilizes, and implants itself in the uterus. When the cells start multiplying in the uterus after implantation, one structure is formed as an embryo, and others become the placenta. Once the implantation is successful and the embryo has been formed, you will miss your menstrual period.

2. Embryonic Stage

The period between the third to eighth week of pregnancy is commonly known as the Embryonic Stage. During this phase, the blastocyst, which is formed when the fertilized egg cells multiply, begins to develop unique traits and becomes an embryo. It is during this period that the various structures and organs, including the neural tube, mouth, head, eyes, limbs, and heart, begin to develop and function. Morning sickness usually kicks in at this point.

3. Fetal Stage

The fetal stage begins during the ninth week and continues until birth. During this stage, the embryo grows into a healthy fetus. The organs continue to grow, and your doctor can determine the sex of the fetus through an ultrasound. As the fetus grows, they will start moving their limbs. You will be able to feel the movements from the 20th week. Significant fetal growth occurs during this stage of pregnancy.

Health and Care During Intrauterine Pregnancy

Intrauterine pregnancy is a normal one as far as the fertilized egg reaches the uterus and the fetus gets a normal heartbeat. The following are some of the essential tips you need to remember to have a healthy and safe Intrauterine pregnancy.

1. Healthy and Balanced Diet

The food that you eat plays a significant role in keeping your pregnancy healthy. Choose to eat more healthy food and avoid junk as much as possible. Also, try to include antioxidants in your diet. For a sustainable intrauterine pregnancy, you can trust on the green leafy vegetables.

2. Avoid Smoking

Quitting or avoiding smoking is healthy not only during pregnancy but also can contribute to your general well-being.

3. Prenatal care

You need to attend all your prenatal appointments and get yourself checked at the right time. It helps you to keep track of the health and growth of the little one. Any complications can be identified early and quickly.

4. Medications

Make sure to take the medications prescribed by the doctor at the proper dosages.

If you have any pre-existing conditions or have a failed pregnancy earlier, it is essential to talk to your doctor and take precautions well ahead.

Possible Complications and Their Management

Intrauterine pregnancies are the standard form of getting conceived. But, certain possible complications might complicate the journey of pregnancy.

1. Chemical Pregnancy

A chemical pregnancy condition where the egg does not implant properly.

2. Blighted Ovum

Blighted ovum is a condition where the fertilized egg stops growing after a point of time in the uterus

3. Ectopic Pregnancy

An ectopic pregnancy is a condition where the egg implants itself in the fallopian tube and not in the uterus.

4. Miscarriage

Miscarriage occurs when the fertilized egg does not grow well and expels from the body before 20 weeks of gestation.

5. Stillbirth

Loss of pregnancy after crossing 20 weeks.
