Early Signs of Twins Pregnancy: First Two Weeks!

The first two weeks of pregnancy are unusual because technically during week one, you are not yet pregnant. Doctors count when you become pregnant on the first day of your previous menstrual cycle. This is because a woman starts ovulating about week two or three after the last menstrual cycle. This is when a woman’s body releases an egg and a partner’s sperm fertilizes the egg. If a woman releases more than one egg and a man’s sperm fertilizes both eggs, she conceives twins. If the fertilized embryo splits into two, twins can result as well.

While the changes may be only very small when it comes to the early signs of twins pregnancy in the first two weeks, it’s possible that a woman could start to notice some small signs that her body is starting to grow not one, but two fetuses. Because her body is trying to support the growth of more than one baby, these symptoms can sometimes seem more noticeable. Below are some of the possible early signs of twins pregnancy in the first two weeks.

Missed Period

One of the earliest signs a woman is pregnant is that she misses her period. Sometimes this can be deceiving because a woman may initially experience some spotting or light bleeding when she first becomes pregnant. This bleeding can be mistaken for a lighter than normal period. Spotting can be especially common during a twins’ pregnancy, according to Abdulla Al-Khan, MD, the director and chief of maternal and fetal medicine and surgery at Hackensack University Medical Center in New Jersey interviewed on WebMD.

“A little spotting in the absence of cramps is reassuring, but when you are cramping, passing clots, and actively bleeding, that is a sign that’s something is happening and you should seek medical advice,” Dr. Al-Khan says.

Also, some women may not have regular periods, which may lead them to be uncertain if they are missing their period or just late on it.

Home pregnancy tests are available, but most of them won’t sense a woman is pregnant until about a week after she missed her period. If a woman thinks she is pregnant, yet the first pregnancy test is negative, re-taking the test about three days later can more accurately reveal if she is pregnant or not after she has missed her period.

Changes in Mood

Sometimes the hormone fluctuations associated with pregnancy can cause a woman to experience changes in mood. These mood changes could be anything from feeling very emotional and sad to being quicker to become frustrated and/or angry. These are similar to the mood changes she may experience if she commonly experiences premenstrual syndrome or PMS.


An increase in hormones to support the growth of twins can cause a woman to feel more tired than usual. On the outside, she is going about her daily routine, but on the inside, her body is beginning the process of supporting two new lives. In addition to fatigue from the extra daily workload, a woman may also feel more tired due to an increase in the hormone progesterone. This hormone, known as the pregnancy hormone, can lead to increased feelings of sleepiness. If a woman is sticking to her regular routine, yet feeling extremely exhausted, pregnancy could be the underlying cause.

Morning Sickness

Moms pregnant with twins tend to experience higher incidences of morning sickness, according to WebMD. Women pregnant with twins experience higher rates of the hormones human chorionic gonadotropin (hCG), which is associated with causing increased rates of nausea and vomiting. These hormone levels will typically even out about 12 to 14 weeks after a woman becomes pregnant.

However, if a woman experiences strong and severe instances of morning sickness where she cannot keep any food or anything to drink down, she should call her doctor. This can be a sign of the condition hyperemesis gravidarum, which is a more severe version of morning sickness. This may cause a woman to require hospitalization to receive intravenous fluids and medications.

Breast Tenderness

Changes in your breasts may be one of the first signs of a twins pregnancy. The increase in hormones associated with pregnancy may start transferring to your breasts. This will increase blood flow. As a result, a person may experience greater episodes of breast tingling and breast tenderness. Sometimes extra breast soreness is mistaken as a symptom of an impending menstrual period. However, breast tenderness is especially common in the two weeks after a woman conceives or becomes pregnant. A woman may notice that her bra does not fit as well as it once did and may feel uncomfortable.

Conclusions on the Early Signs of Twins Pregnancy in the First Two Weeks

If a woman is experiencing early signs of a twins pregnancy, now is the time to ensure she is doing all that she can to support the healthy growth of both of her babies. According to WebMD, women who are expecting twins require more folic acid than women who are pregnant with only one baby. The recommendations for folic acid are 1 milligram per day for twins and 0.4 milligrams per day for single pregnancies. Folic acid is a form of B vitamin and has been linked with helping prevent neural tube defects, such as spina bifida.

Additionally, women need more calories on a daily basis to grow her twin babies. This is usually about 500 calories a day. This is roughly the equivalent of two bowls of cereal, plus low-fat milk and eating a small banana. When making the decision on what to eat, protein-containing products are especially beneficial because they can help to prevent anemia, which mothers of twins are prone to. Examples of these foods include fish, poultry, beans, egg whites, and nuts. Making these healthy choices early can help a women enjoy a healthy pregnancy from its earliest stages.
