Finding out you're pregnant with twins The only definite way to find out whether you're having twins or other multiples is to have an ultrasound scan. The best time to have this ultrasound is at 10-12 weeks of pregnancy.
How soon can you tell you're pregnant with twins? Your doctor won't be able to tell for sure until your first trimester ultrasound, which is usually done between 6 and 9 weeks of pregnancy but can be done any time between week 14.
If your twins are fraternal — meaning, two different eggs were fertilized — there will be a separate gestational sac for each baby. If you're estimating your pregnancy accurately, multiple sacs should be pretty visible on a transvaginal ultrasound at 7 weeks.
With a twin pregnancy, your body makes high levels of pregnancy hormones. So morning sickness may come on earlier and stronger than if you were carrying a single baby. You may also have earlier and more intense symptoms from pregnancy, like swelling, heartburn, leg cramps, bladder discomfort, and sleep problems.
Morning sickness tends to be more severe for moms having twins than moms having singletons. Hearing heartbeats early on: Your doctor would be able to hear 2 sets of heartbeats as early as 10-12 weeks into pregnancy. Higher water retention: There is a high level of water retention when you are having twins.
It is estimated that 1 in 250 natural pregnancies will naturally result in twins. While twin pregnancies can happen by chance, there are some factors that may increase your odds of having two babies at the same time. Let's learn about twins!
Factors that increase the chance of twins include: consuming high amounts of dairy foods, being over the age of 30, and conceiving while breastfeeding. Many fertility drugs including Clomid, Gonal-F, and Follistim also increase the odds of a twin pregnancy.
However, for a given pregnancy, only the mother's genetics matter. Fraternal twins happen when two eggs are simultaneously fertilized instead of just one. A father's genes can't make a woman release two eggs.
Age. According to the Office on Women's Health , women who are aged 30 years or older are more likely to conceive twins. The reason for this is that women of this age are more likely than younger women to release more than one egg during their reproductive cycle.
Everyone has the same chance of having identical twins: about 1 in 250. Identical twins do not run in families. But there are some factors that make having non-identical twins more likely: non-identical twins are more common in some ethnic groups, with the highest rate among Nigerians and the lowest among Japanese.
Early signs of a twin pregnancy include severe morning sickness, quick weight gain, and more breast tenderness. You may also notice an increased appetite or extreme fatigue. Plus, those who have a twin pregnancy may begin showing sooner.
For a given pregnancy, the odds of conceiving fraternal twins are only determined by the mother's genetics, not the father's. Fraternal twins happen when two eggs are simultaneously fertilised instead of just one.
A little more than half of twin pregnancies end in preterm delivery (before 37 weeks). While 40 weeks is the full gestation period of the average pregnancy, most twin pregnancies are delivered at approximately 36 weeks (range 32-38 weeks depending on the type of twin pregnancy).
You can take maternity leave any time from 11 weeks before the start of the week when your babies are due. Your obstetrician will give you an idea of when your babies are due, as twins or more tend to arrive earlier than singleton babies. Mums-to-be of twins usually start their maternity leave at 26 weeks.
These standard charts may not describe optimal weight gain patterns because recommended delivery gestational age for twins is between 37 and 42 weeks with average twin birth weights ≥2500 g to reduce mortality and morbidity.
The risk is highest in the first trimester, although it drops significantly once a fetal heartbeat is established, Roshan says. A 2003 study shows that the risk for twin miscarriage once the babies' heart beats are detected is around 7 percent.
Several factors for causes of embryo splitting were suggested, including maternal age, prolonged embryo culture, ovarian stimulation, and zona pellucida (ZP) manipulation [6].
The quick answer to this question is that, in a twin pregnancy, it is the mother's genes that determine twins. First up, giving birth to identical twins is not genetic, but conceiving fraternal twins is. The mother may have the genetic trait of releasing two eggs in one menstrual cycle.
Is there a third type? Traditionally, the science around twins has taught that identical and fraternal are the only two types. But a third type might exist, called polar body or half-identical twins.
However, home pregnancy tests won't confirm if twins are present, only the presence of hCG. It takes around 2 weeks after conception for hCG to be detected in a hCG pregnancy test. Low levels of hCG may be detected in a woman's blood 8-11 days after conception.
Do Twins Skip Generations? Many people believe twins skip a generation, but that's just a myth. The idea that twins skip generations likely comes from the fact that the genetic factors contributing to twins only come from the gestational parent's side.
If you're carrying multiples, you can expect: More-frequent checkups. You'll see your health care provider often to track your babies' growth and development, monitor your health, and watch for signs of preterm labor. You might need frequent ultrasounds or other tests, especially as your pregnancy progresses.
Monoamniotic-monochorionic Twins
These types of twins share a chorion, placenta, and an amniotic sac. This is the rarest type of twin, and it means a riskier pregnancy as the babies can get tangled in their own umbilical cords.
It's estimated that 1 in 250 pregnancies results in twins naturally, and there are two ways to conceive them.
