Twins When hCG Is Increasing Too Fast

In most pregnancies, the normal hCG rise is at least 60% over 48 hours. In twins, it may rise much more, but it's not possible to diagnose a twin pregnancy just from the hCG levels alone. The hCG can rise manyfold even without twins.

  • In most normal pregnancies at hCG levels below 1,200 mIU/ml, the hCG level usually doubles every 48-72 hours, and it normally increases by at least 60% every two days.
  • In early pregnancy, a 48-hour increase of hCG by 35% can still be considered normal.
  • As your pregnancy progresses, the HCG level increase slows down significantly.
  • Between 1,200 and 6,000 mIU/ml serum, the hCG level usually takes 72-96 hours to double.
  • Above 6,000 mIU/ml, the hCG levels often take over four or more days to double.
  • In general, when the hCG level reaches 7200 mIU/ml, a yolk sac should be seen.
  • At an hCG level greater than 10,800 mIU/ml, there should be a visible embryo with a heartbeat.

There is no sufficient scientific evidence that with twins there is always a faster-than-usual rise in hCG. Normal hCG values can vary up to 20 times in normal pregnancies. Variations in hCG increases are not necessarily a sign that the pregnancy is abnormal or that there are two or more fetuses.

Role Of HCG Level In Twin Pregnancy

The body does not produce HCG; rather, it comes purely from the developing baby. Each developing baby secretes a normal amount of HCG, which is double the normal amount in cases of twins compared to single pregnancy. These hormones work collectively to thicken the lining of the uterus, which supports the baby during pregnancy.

Progesterone is a hormone that stimulates the uterus to prepare for pregnancy. It is produced by the corpus luteum (an endocrine gland within the ovary). The purpose of HCG is to keep progesterone levels in balance until the placenta is developed enough to produce its own progesterone.

When expecting a twin, the HCG level increases dramatically during the first three months of pregnancy compared to single pregnancy, making it faster to detect HCG in blood and urine test. It doubles every 48 to 72 hours.

More Morning Sickness

There is a saying about twins: "Twice as sick, three times as tired, and four times the weight gain." But this is, in many ways, an old wives' tale.

Statistically, moms of multiples may experience more morning sickness, but using the degree of morning sickness as an estimate that you are carrying twins isn't necessarily very helpful.

Overall, about half of women experience some amount of nausea and vomiting with single pregnancies, and up to 1 percent experience hyperemesis gravidarum, a form of severe morning sickness. At the same time, some moms of twins and triplets say they have no morning sickness.

Also, with a first baby, a woman doesn't have a reference point to compare her degree of nausea. But with second babies and on, around 15 percent of women reported more morning sickness with multiples than with previous single pregnancies.

Finally, another potential sign is that in women carrying multiples, nausea may begin quite early, even before a pregnancy test turns positive. Again, though, this is not a fact, simply an observation.


Not every woman is a candidate for HCG monitoring. Many women never have their levels evaluated beyond a urine test to confirm pregnancy. However, some doctors do recommend testing, particularly in situations where there has been conception assistance or a history of miscarriage.

HCG is the substance detected by common over-the-counter pregnancy tests to determine if a woman is pregnant or not. These tests measure the amount of HCG in a urine sample to determine whether there is enough of the hormone to indicate pregnancy.

But HCG monitoring of a blood sample provides a more comprehensive picture of the woman's status. It not only indicates whether an egg is fertilized, but can be used to determine whether the fertilized egg, implanted in the uterus, is developing into an embryo. An HCG blood test can also suggest the presence of more than one embryo.

A single HCG measurement doesn't tell the story. Rather, samples are taken every few days during the early weeks of pregnancy and compared. With each passing day, increasing amounts of the hormone are detectable in the pregnant mother's system. HCG production peaks toward the end of the first trimester, so it is generally monitored only in the first few weeks of pregnancy.

Positive Beta Test Results Can Only Confirm That You’re Pregnant

Here’s the short answer to my question: beta hCG levels are only indicative of whether or not you’re pregnant, not how many embryos you are carrying. Beta levels of more than 5-10 at two weeks post ovulation mean that you’re pregnant, though low levels might indicate an ectopic pregnancy or miscarriage. Once the beta test confirmed you’re pregnant, though, it’s pretty much run its course. To know how many babies you’re having, you’ll need to wait until you get an ultrasound.

This is where we get into the gray area of probability, though. Yes, to know for sure whether you’re having one, two or more babies, you need an ultrasound. But what if you just wanted to get a sense of how likely you are to be having more than one? Clearly, when the nurse said I was very pregnant she suspected something was going on (spoiler: she was right, I had twins…).
