When a fertilized egg implants and begins to develop inside the uterus, where it is expected to be, this is known as an intrauterine pregnancy (IUP). Pregnancy can only develop and continue to full term inside the uterus.
An intrauterine pregnancy detected by ultrasonography indicates that the pregnancy is growing correctly.
Ectopic pregnancies are not viable, which means they will not result in the delivery of a child. Ectopic pregnancies develop elsewhere in the female reproductive tract (such as the cervix, ovary, or fallopian tubes).
To locate the pregnancy and rule out any difficulties, possible worrying early pregnancy symptoms including abdominal or pelvic pain and vaginal bleeding should be examined.
Explaining Intrauterine Pregnancy
When an egg is fertilized during spontaneous conception, it continues to travel down the fallopian tube, propelled by tiny projections resembling fingers called fimbriae, towards the uterus, where it is most likely to implant in the uterine lining.
The uterus is built to accommodate a developing pregnancy. It can expand to accommodate the growing fetus and has a sufficient blood supply to support pregnancy.
An extrauterine or ectopic pregnancy is a condition in which the fertilized egg implants itself somewhere other than the uterus. The most frequent location for ectopic pregnancy is the fallopian tube, which is not intended to grow, enlarge, or in any other way accommodate a pregnancy.
A fertilized egg is made to be invasive by nature. No matter where it is, a developmental timeline is started. The process of implantation may begin in the wrong place if the fimbriae are slow to transport a fertilized egg out of the tube or are unable to do so.
The lack of room and the tube’s inability to extend can lead to the tube bursting as the embryo develops and tries to produce a placenta. This rupture, which may result in bleeding and stomach pain, has to be treated by a doctor very far away since it may be fatal.
Spotting an Intrauterine Pregnancy
An ultrasound scan can be used to pinpoint where a pregnancy is. Intrauterine pregnancy may be identified by the following:
A Visible Yolk Sac
Around 5.5 weeks into the pregnancy, a transvaginal ultrasound can show the yolk sac. Up until the placenta develops, the developing embryo is nourished by the yolk sac. Up until an embryo can be seen, it is the sole factor that can certify a live intrauterine pregnancy.
An Embryo with Fatal Heart Activity
As early as six weeks into pregnancy, fetal heart activity can be identified. Over the following weeks, a heart rate increase of 100 to 120 beats per minute (BPM) is usual.
- A rate below 80 bpm before 6.3 weeks indicates a poor prognosis and an elevated risk of miscarriage in the first trimester.
- At 6.3–7 weeks, 120 bpm indicates a bad prognosis; at less than 100 bpm, the prognosis is particularly poor and the risk of miscarriage is elevated.
Intrauterine Pregnancy Diagnosis
To better define an intrauterine pregnancy, utilize the phrases below.
- A gestational sac that is inside the uterus and contains either a yolk sac or an embryo/fetal pole with fetal cardiac activity is referred to as a live intrauterine pregnancy. This pregnancy is progressing normally as of right now.
- A single gestational sac that is in the uterus and contains either a single yolk sac or a single fetal pole with fetal cardiac activity is referred to as a single live intrauterine pregnancy. This pregnancy, which is currently one-fetus, is progressing normally.
- When a scan reveals a gestational sac in the uterus but it is too early to detect the embryo or fetal heartbeat, the pregnancy is intrauterine. To determine whether the pregnancy is developing normally, more data (usually another ultrasound scan) is required.
Causes of Intrauterine Pregnancy
Here are a few possible reasons why an early intrauterine pregnancy could fail or end in miscarriage:
Abnormal Chromosomes or Genes
Most miscarriages are caused by faulty fetal growth. An entirely random phenomena, missing or extra chromosomes are thought to be responsible for about 50% of miscarriages. This develops during the division and growth of your embryo and is not inherited from either parent. Chromosomal anomalies may result in:
Infant death within the womb
In this case, the fetus would stop growing and pass away before any signs of pregnancy loss would show.
Never does the embryo start to develop.
The father is the source of the embryo’s two sets of chromosomes. The lack of (or partial) fetal development and aberrant placental tissues are further characteristics of a molar pregnancy. The mother’s chromosomes are still present in partial molar pregnancies, but the male still transmits two sets of chromosomes.
A prior maternal medical issue may occasionally cause a miscarriage. Among the contributing elements are:
- unmanageable diabetes
- hormonal problems
- significant infections
- thyroid condition
- uterine or cervical issues
- previous miscarriages
- Use of drugs, alcohol, and tobacco
- Sexual activity
- Continually working
Avoiding Intrauterine Pregnancy
To maintain the happiness and health of both you and your unborn child, think about the following lifestyle factors:
- Consume a healthy, balanced diet that is high in fruit and vegetables
- Avoid using drugs, drinking, and smoking
- Maintain a healthy weight before trying for a baby
- Before becoming pregnant, treat any issues that have been found, such as antiphospholipid syndrome (APS) or a weak cervix
Consulting A Doctor
When a pregnancy test yields positive findings, talk to your doctor about any potential medical issues. Spotting and bleeding in the vagina are typical symptoms of an early intrauterine pregnancy failure. Please seek immediate medical assistance if you notice this.
How do you define intrauterine pregnancy? Only an ultrasound can accurately detect this complicated illness. To validate your doctor’s first concerns of early intrauterine pregnancy, a follow-up screening is typically required. Remember that the likelihood of an intrauterine pregnancy failing is increased by specific maternal health issues and the existence of defective chromosomes or genes.
