1. Age of a mother.

This is one of the reasons of increasing amount of twins’ birth – a worldwide tendency to late deliveries. A probability of birth of two and more babies increases, if a mother is older than 35 years. (By the way, this chance increases even more after 50 years). Unfortunately, if you’re less than 25 years, your chances are half of chances of those who are 35. The matter is that with age, ovulations take place not during each cycle – and this is quite normal. As a result, free hormones, affecting ovulation, accumulate and release during the following cycle, stimulating coming out of several ovules at once.

2. Inheritance.

If some of your or your husband’s relatives has twins, then your probability of giving birth to several babies at once is extremely high (especially, if you inherited this trait from your mother). And, regardless of common opinion, this does not necessarily take place in one generation – you can inherit a gene, which is responsible for formation of several ovules, suitable for insemination, in your organism.

3. Genesial technologies.

Often women, who were prescribed hormonal medicines during sterility treatment or while preparation to artificial extracorporal fertilization, get plural pregnancy. Hormonal medicines stimulate ovulation in the midst of a cycle and, if a woman receives overdose of a medicine, then several ovules come out of ovary follicle at once, not just one. As a rule, doctors “remove” excess ovules. Burt sometimes women refuse from it, due to religious or other motives. In USA and Israel there were cases, when women gave birth to 6 or 7 babies at once.

Sings of plural pregnancy

It’s very easy to determine a quantity of babies you’re going to give birth to – you can do it with the help of echography on 5-6th week of pregnancy, but there’re such situations, when you cannot pass through echography. So, it will be good for you to learn some signs of pregnancy with twins. Moreover, unfortunately, doctors not always can give you an exact answer about your pregnancy during the first 10-12 days.

Psychological factor. You should not ignore your intuition. Many women can be assured in the fact that they are pregnant with twins since the moment of conception already. Often mothers of twins admit that they knew about their forth-coming birth on the earliest terms of pregnancy. If you feel, you’re expecting twins, tell your doctor about it for sure.

High biochemical indexes. Women pregnant with twins have increased indexes of some biochemical tests. For example, content of alpha fetoprotein – it produces a growing fetus and come to mother’s blood. Or a high content of a hormone HCG (human chorionic gonadotropin), which supports pregnancy. While placenta is developing, its presence can be determined in blood or urine even before delay of menstruation, and lots of pregnancy tests are based on its indexes.

Intensive morning sickness and/or vomiting. More heightened, in comparison with usual pregnancy, content of hormone HCG (pregnancy hormone) can increase morning sickness. Sickness, sometimes accompanied by vomiting, can already appear a week after conception, i.e. even before your usual menstrual cycle begins. Sickness appear more often in the morning, but it’s also possible in any other time of a day.

Intensification of other pregnancy sings. Many (but not all) women, expecting twins, suffer from other intensified sings of pregnancy – due to a significant increase of hormones, in comparison with usual pregnancy. For example, they feel heightened breast sensibility, more frequent impulses of urination, extreme tiredness and hunger. In the second term a woman may suffer from strong breathlessness, hands and legs spasms, sudden increase in weight and belly sizes, and an intensive stir of fetus. Hemoglobin decrease or anemia – are also usual events for plural pregnancy. And in general, this is not surprising, as during such pregnancy a load on a future mother’s organism increases in several times, depending on the quantity of babies she’s bearing. Unfortunately, this means that complications are much more often met during such pregnancy.

Quick weight increase since the first days of pregnancy. By the way, this is one of the first sings of two babies’ presence in a woman’s uterus. This is absolutely normal: double nutrition plays an important role during the first term of pregnancy. And a quick weight increase is necessary.

High physiological indexes. During the first medical examination doctors will be already able to tell you that your uterus size is little bigger for your assumed term of pregnancy. This tendency will remain for the whole term of pregnancy. Other physiological indexes will be bigger too: circularity of belly through navel, height of uterine fundus standing and others.

Heartbeat of two hearts can be heard. When a doctor begins listening to a baby’s heartbeat, he will hear beating of two hearts, instead of one. Two separate heartbeats can be heard on the 13th week of pregnancy already, by the 28th week a doctor will be able to determine 3-4 large parts of body (head and bum) and many small ones by touch.
