"Generally when you are pregnant with twins, fetal movements become more noticeable at weeks 18 through 20 of pregnancy, and the same is true in singleton pregnancies," Al-Khan says.
#1 Fraternal twins can be conceived as much as 24 days apart
For this reason, fraternal twins can be conceived a few weeks apart, though they generally will be born at the same time.When will I know if I'm having twins? A heartbeat (or two!) can sometimes be heard during a vaginal ultrasound at around six weeks of pregnancy, but the presence of more than one baby may be determined with more accuracy during an ultrasound exam at around 12 weeks.
No.That's not all, Monga says. Moms pregnant with twins complain of more back pain, sleeping difficulties, and heartburn than moms who are carrying one child. Moms pregnant with twins also have a higher rate of maternal anemia and a higher rate of postpartum hemorrhage (bleeding) after delivery.
August had the most births each year from 1990 to 2006 except for six years (1992, 1993, 1997, 1998, 2003 and 2004) when it was edged out by July, according to National Center for Health Statistics.
Just like singleton babies, twins can sometimes get super-active in the womb. But not to worry — there's no real threat from it! Babies can kick or even hit each other (yes, really) in utero, but the good news is the amniotic fluid acts as a cushion to protect them from actually getting hurt by any of it.
It's not unheard of for a twin pregnancy to go undetected in early ultrasounds (say, around 10 weeks). But once you reach the midway point of your pregnancy and have your 20-week anatomy scan, you can be 99.99 percent confident about how many babies to expect at your delivery.
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!
Many twin pregnancies are discovered by ultrasound. Your doctor may suspect you are pregnant with more than one baby when checking your baby's heart rate or having alpha-fetoprotein levels tested. If your doctor suspects you may be pregnant with multiples, they will likely recommend you go for an ultrasound.
Eat well, take gentle exercise, drink lots of fluid and, if you feel stressed, ask for support from friends and family, or talk to your midwife or doctor. Some people think that if you are pregnant with twins, you need a lot of extra food.
Many pregnancy symptoms are caused by hormonal changes. It makes sense that women expecting twins—who have even more substantial hormonal changes—may experience more severe symptoms.
In many cases there will be multiple amniotic sacs too, although identical twins may be sharing one. You will usually be able to listen to each baby's heartbeat and to take a close look at them on the screen while they are being measured and examined.
Identical twinning and family heredityIdentical twins happen when a single embryo splits in two soon after fertilisation. This is why identical twins have identical DNA. They came from the same fertilised egg. Since embryo splitting is a random spontaneous event that happens by chance, it doesn't run in families.
If twins are a boy and a girl, clearly they are fraternal twins, as they do not have the same DNA. A boy has XY chromosomes and a girl has XX chromosomes. Girl-boy twins occur when one X egg is fertilized with an X sperm, and a Y sperm fertilizes the other X egg.
Factors that increase the chance of twins include: consuming high amounts of dairy foods and conceiving over the age of 30, and while breastfeeding. Many fertility drugs including Clomid, Gonal-F, and Follistim increase the odds of a twin pregnancy.
Types of Twins: Fraternal, Identical, and More
- Fraternal Twins (Dizygotic)
- Identical Twins (Monozygotic)
- Conjoined Twins.

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.
