A miscarriage, also known as natural or spontaneous abortion, is an involuntary embryo loss that occurs before the 20th week of pregnancy, or the loss of a fetus that weighs 500 grams or less. If it happens later, it’s considered a preterm birth with risk of stillbirth.
It’s important for the pregnant woman not to blame the miscarriage on herself, as the cause behind is not usually related to the mother, but on chromosomal abnormalities in the fetus.
Acording to the Merriam-Webster Dictionary, the following is the meaning of the noun miscarriage:
Spontaneous expulsion of a human fetus before it is viable and especially between the 12th and 28th weeks of gestation.
Taking this definition into account, we should not confuse it with an abortion, which often refers to the induced expulsion of a human fetus.
Statistical data shows that most miscarriages occur during the first trimester of pregnancy. More often than not, the woman isn’t even aware that she was expecting.
A miscarriage can lead to serious consequences or side effects for the health of the woman, both at the physical and psychological levels. A miscarriage is, unfortunately, a dramatic scenario that causes significant distress in prospective parents.
Recovering from a miscarriage can take several weeks or even months. Most women have their periods again within 4 to 6 weeks after having miscarried.
The most complicated after going through a miscarriage is to overcome the psychological impact and avoid depression and anxiety. Miscarrying severely affects prospective mothers not only on the emotional side, but also because the hormones levels change sharply in a short period of time.
It is estimated that about 10% of women who experience an spontaneous abortion may have acute stress disorder and up to 1% may have post-traumatic stress disorder.
There’s no reason for you to be ashamed or afraid after a miscarriage. You can join a support group or get couple therapy if you need it to cope with this situation.
We distinguish several types of miscarriage or spontaneous abortion based on the following factors:
- Sporadic vs. recurrent
- If the pregnancy loss occurs spontaneously or repeatedly.
- Clinical vs. subclinical
- If it occurs at an advanced gestational age or very early, that is, after embryo implantation.
- Anembryonic vs. embryonic
- When the embryonic sac cannot be seen on an ultrasound yet or, on the contrary, the embryo is seen but stops developing.
- Complete vs. incomplete
- Depending on whether your body expels all the products of pregnancy or not.

The causes of miscarriage are typically related to the fetus, but they can be associated with the mother-to-be as well. Let’s see some examples of each:
- Fetal causes
- The presence of chromosomal abnormalities in the fetus is the leading cause of spontaneous abortion and early pregnancy loss.
- Maternal causes
- Uterine malformations, infections, autoimmune diseases or endocrine disorders can lead to miscarriage.
Complications during pregnancy can lead to the loss of the pregnancy as well. However, the severity of these complications is higher when the following risk factors are involved:
- An unhealthy or incomplete diet. You should take special care with the foods you eat during pregnancy.
- Hormonal imbalances
- Sexually Transmitted Diseases (STDs)
- Health conditions, including congenital heart diseases, kidney diseases, diabetes, or thyroid problems.
- Running a high fever
- Poor IUD positioning at the time of conception
- Uterine malformations

Although one can notice certain symptoms or signs directly associated with miscarriage, it is important to know that it doesn’t happen in all cases. Having symptoms of miscarriage is just a warning sign.
The following are the most common symptoms associated with miscarriage:
- Heavy vaginal bleeding
- Moderate-to-severe pain of unknown origin
- Abdominal pain
- General weakness or lethargy
When a woman has signs of miscarriage, she should contact her doctor at once to look for the best solution and prevent the risk of miscarriage from becoming an actual miscarriage.
When a woman is at risk of miscarrying, rest in bed is crucial. Also, your doctor may prescribe you progesterone capsules, although the effectiveness of this practice has been questioned in several scientific studies.
If miscarriage finally occurs, no specific treatment is necessary. Your body will expel the fetus naturally in the form of bleeding. If this doesn’t happen, the remaining tissue will be removed by means of D&C (Dilation & Curettage).
Using an anesthetic, D&C involves the dilation of the cervix and subsequent removal of the remaining tissue that may still be in the uterus.
If necessary, your doctor may prescribe you medications such as Misoprostol, which can cause uterine contractions that help expel the remaining tissue. Misoprostol has, however, a series of side effects that one should not overlook:
- Vaginal bleeding
The materials expelled spontaneously or as a consequence of scratching the uterine cavity is sent to the laboratory so that a specialist can evaluate it. The goal is to find the cause of the miscarriage and prevent it from happening again.

The first prevention measure for miscarriage is to take care of yourself from the very beginning of your pregnancy. We have mentioned the main risk factors for miscarriage above, so we recommend that you avoid these habits at all costs to reduce the chances of miscarriage.
If you are planning a pregnancy, we strongly recommend that you treat first any disease or health problem that is directly associated to miscarriage or can be a risk factor.
High blood pressure, obesity, and diabetes can increase the risk of miscarriage if untreated. Examining whether the intended mother has had an infection such as toxoplasmosis or rubeola, which can cause severe fetal alterations leading to pregnancy loss.
Other disorders that should be taken into account when trying to conceive, due to its direct relation with spontaneous abortions, are uterine malformations and immunological diseases.
Leading a healthy lifestyle, including a balanced diet and moderate exercise, is crucial as well. Moreover, regular prenatal care, attending every prenatal visit, and following the doctor’s instructions strictly, is the best way to avoid potential pregnancy complications.

What are normal hCG levels after miscarriage?
After a miscarriage, hCG levels may vary depending on the week of pregnancy in which it happens. For example, if it happened on week 6, hCG levels would be expected to range between 1.080 mUI/ml and 56.500 mUI/ml.
Why do miscarriages keep happening?
The truth is, sometimes the cause of recurrent pregnancy loss (RPL) cannot be found. The good news in these cases is that there’s always a chance that a successful pregnancy happens next time.
There are, however, some health conditions that are known to increase a woman’s chances of miscarrying. Although they are uncommon, the following are some conditions that are known to lead to RPL:
- Antiphospholipid syndrome (APS)
- Genetic problems
- Problems with your womb
- Bacterial vaginosis
- Polycystic ovaries
- Some lifestyle factors
