Pregnancy hormone levels in twins in the second week
Below I will explain how pregnancy hormone levels change naturally at different times during pregnancy: They range from 25 to 450 in the first weeks. From the fourth to the ninth week, they rise to between 450 and 142,500. From the thirteenth to the sixteenth week, the levels are between 4500 and 132500.
At the beginning of the second week of pregnancy, it is normal for the hCG level to range between 100 and 500 milli-international units per milliliter of blood. If a woman is pregnant with twins, this level may be higher. These values vary from woman to woman based on several factors such as genetics and how the pregnancy occurred. It should be noted that hCG measurements do not always provide a reliable indication of a multiple pregnancy, as values may vary in cases of twin pregnancies.
In which month do I know that I am pregnant with twins?
A twin pregnancy can usually be detected in the third or fourth month of pregnancy, which is between the tenth and fourteenth week.
Sometimes, twins can be detected earlier, but this is rare and the second fetus may not be seen that early. To detect a twin pregnancy, women use an ultrasound, or sonar. This tool uses high-frequency sound waves to create an image of the fetuses and determine if there is more than one fetus.
Ultrasound is the best and most accurate way to check for twin pregnancy, but it is worth noting that its use may be challenged if there are more than two fetuses. Ultrasound can be performed either through the abdomen or the vagina, and doctors usually prefer the abdominal examination except in the early stages of pregnancy when the vaginal examination is more accurate.
What is the pregnancy hormone level for twins in the third week?
To check the level of HCG hormone in a woman’s body, doctors resort to conducting blood tests. This hormone is known to increase significantly in early pregnancy, as it can double every 29 to 52 hours. However, there are cases in which the results show either a decrease in the levels of this hormone or a failure to double as expected in the first weeks, which may indicate problems such as the risk of miscarriage, damage to the egg, or even an ectopic pregnancy.
On the other hand, an abnormally high level of this hormone may be an indication of certain pregnancy complications such as a placental polyp or molar pregnancy. Studies show that the normal lower level of pregnancy hormone is 17 Miu/l when carrying twins in the third week, and it can rise to 80 IU/ml, which are much higher than those recorded for a single pregnancy, where they reach about 7 Miu/l.
It is also important to know that the level of the pregnancy hormone increases significantly in the early stages, reaching 1666 miu/l in the fourth week of pregnancy if pregnancy occurs on the fourth day of ovulation. If pregnancy occurs on the 14th day of ovulation, the level of HCG is expected to reach a peak of 8270 miu/l. In the case of a twin pregnancy, the level of this hormone increases very significantly, and may reach five times the rate recorded for a single pregnancy.
Are pregnancy hormone levels higher with twins?
We would like to share an important piece of information regarding twin pregnancy and its effect on pregnancy hormone levels. When comparing twin pregnancy with single pregnancy, it is clear that pregnancy hormone levels show a significant increase in twin pregnancies. Gynecologists confirm that these rates may increase by between 30% and 50%.
However, it is important to note that an increase in the level of this hormone is not necessarily a definitive indication of a twin pregnancy. Since the level of this hormone varies from one woman to another, accurate tests such as ultrasound must be relied upon to confirm a twin pregnancy, which is usually best performed in the sixth week of pregnancy.
Signs of high pregnancy hormone with twins
1. Severe morning sickness
When carrying twins, a pregnant woman may experience symptoms such as nausea and severe vomiting, as a result of the increase in pregnancy hormones in the body.
2. Severe breast pain
During the first months of pregnancy, many women may experience pain in the breast area, which is expected due to the physical changes that occur. In cases of twin pregnancy, this feeling is enhanced, as the body prepares to provide food for two children, which leads to increased pressure and stimulation of this area in an intense way.
3. Frequent urination
Feeling the need to go to the bathroom and urinate more frequently is usually more noticeable in twin pregnancies than in single pregnancies. This is due to a rapid rise in levels of the pregnancy hormone known as “hCG”, which affects the body in this way.
4. More swelling
Pregnant women with twins tend to notice more swelling in the ankles and joints than others, due to the amount of excess water accumulated in the body. This swelling becomes more noticeable in the middle of the pregnancy and can sometimes be a sign of certain complications that should be watched out for.
5. Fatigue and mood swings
During pregnancy, progesterone levels increase significantly, which helps support the growth of twins. This increase is also accompanied by an increase in metabolic rate, which is the speed at which the human body burns energy. These two factors together may be the reason why pregnant women feel so tired.

How do you know if you are pregnant with twins?
There are several signs that make women wonder if they are expecting twins. Here are some ways to help detect a pregnancy with more than one fetus:
– AFP test: The human fetus produces a special protein that can be measured through a specific test called the AFP test. High levels of this protein can be an indication of the presence of more than one fetus.
- Ultrasound examination: This examination can clearly confirm the presence of twins after the tenth to twelfth week of pregnancy.
– Detecting the heartbeat: Between the fifth and eighth week, the fetal heartbeat can be heard. By the tenth and twelfth week, it is possible to distinguish between the heartbeats of each fetus individually.
However, high levels of fetal protein should not be relied upon entirely as an indicator of a twin pregnancy, as this increase has other causes that may include:
- Other health problems: such as exposure to some types of cancer, liver cirrhosis, or colon or ulcer problems.
On the other hand, if the levels of pregnancy hormone are low, it may indicate pregnancy concerns such as incorrect calculation of the fertilization date, non-embryonic pregnancy, miscarriage, or ectopic pregnancy.
Ultimately, an ultrasound is the most accurate and reliable way to confirm a twin or multiple pregnancy.
