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).
The American College of Obstetricians and Gynecologists (ACOG), for example, recommends delivery between 34 and 37 weeks for twins with a shared placenta and at 38 weeks for twins with separate placentas. Some other physician groups recommend delivery closer to 39 weeks with separate placentas.
Full-term for twins is the same as full-term for singleton babies, technically: 39 weeks pregnant. But if your twins are born at 37 weeks, that's as close to actual full-term as many twins get. At that point, they have full lung maturity and should be able to leave the hospital within a few days of delivery.
Twin births
Twins are more likely to be born early, often before 38 weeks, so it's important to understand your birth options. Less than 1 in every 2 twin pregnancies continues beyond 37 weeks.
Overall, it is considered that twin delivery should be around 37 weeks for dichorionic twins and 36 weeks for monochorionic twins. With singletons, the neurodevelopmental outcomes are best with delivery at 41 weeks, but the odds of death around the time of delivery are best at weeks 38-39.
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).
More than half of twins are delivered early, or before 37 weeks of pregnancy. In fact, most are delivered around 36 weeks, but delivery any time before 37 weeks of pregnancy is considered preterm.
No.
That's not all, Monga says. Women pregnant with twins complain of more back pain, sleeping difficulties, and heartburn than those who are carrying one child. Being pregnant with twins also carries a higher rate of maternal anemia and a higher rate of postpartum hemorrhage (bleeding) after delivery.
The Reasons For Early Delivery Include:
pre-existing diabetes or gestational diabetes. genital tract infection (e.g. chlamydia, gonorrhea) bleeding from the placenta due to placenta praevia or placental abruption. reduced efficiency of the placenta.
The time between giving birth to your first and second baby varies from woman to woman, but the second baby is usually delivered within about 30 minutes to an hour after the first. In very rare cases, some women deliver 1 twin vaginally and then need a caesarean section to deliver the second twin.
Babies who are born between 32 weeks and 37 weeks generally do very well. If your babies are born early, they are likely to be fine, but they may need to spend time at the special care baby unit (SCBU) or the neonatal intensive care unit (NICU).
6.9 percent in women age 35 to 37. 6.8 percent in women age 38 to 40. 5.1 percent in women age 41 to 42. 5.9 percent in women age 43 and above.
Twin pregnancies are at high risk of stillbirths compared to mothers carrying just one baby. This risk increases 13-fold if twins share the placenta, and five-fold when they have their own placenta. Stillbirth risk also increases as the pregnancy advances so mothers are often delivered before their due date.
The average weight of twins is 2.5kg.
Most practitioners advise women who start their twin pregnancy at a normal weight to gain 37 to 54 pounds. You should gain a little more if you were underweight (between 50 and 62 pounds) and a little less if you were overweight (between 31 and 50 pounds).
Vaginal Birth of Twins
The good news is that even though you have two babies, you only have to labor once. Once the cervix is open, each baby will have its own pushing stage. This means you will have to push twice, but the majority of the time the second twin is born much more easily than the first.
Age. People over 30, and particularly those over age 35, are more likely to conceive twins. 4 This is because the level of follicle-stimulating hormone (FSH) rises as birthing parents get older. FSH is responsible for the development of eggs in the ovaries before they are released.
Since many twin births happen early, the average twin arrives weighing about 5 1/2 pounds.
Tightening or low, dull backache that may be constant or come and go, but changing positions and other comfort measures don't ease it. Menstrual-like cramps or lower abdominal cramping that may feel like gas pains, with or without diarrhea.
The highest risk twin gestation is called monochorionic/monoamniotic, where identical twins share a placenta and an amniotic sac. In addition to the possibility of developing twin-to-twin transfusion syndrome, these babies are at high risk for cord entanglement.
As expected, first-born twins had greater birth weight than second-born twins. With respect to height, first-born twins were slightly taller than second-born twins in childhood.
Monochorionic-monoamniotic twins are identical twins that share both a placenta and an amniotic sac. This is the rarest and highest risk form of twin pregnancies.
What does my baby look like? Your baby, or foetus, is around 47.4cm long from head to heel, and weighs about 2.6kg.
Are twins hereditary? Yes, some types of twins are hereditary, meaning that twins run in families. Heredity on the mother's side ups a couple's odds of conceiving fraternal twins. Fraternal twins are two babies from two different eggs that were released from the ovaries simultaneously.
Expect around nine to 25 days after birth if your twins need to spend some time in the neonatal intensive care unit (NICU). But remember, that not all twins need time in the NICU. Let's talk about the first ideal situation, which is when your twins are born, they're super healthy and they're ready to go home.
