Due Date Calculator

Find out when your Twins are Due. Please note, this is just an estimate, and every pregnancy is different. It is not unusual to deliver before 40 weeks if you are carrying twins.

Twinmom Pregnancy Due Date Calculator

This calculator can help you determine your due date by telling you what your due date would be if you were carrying a single baby. Just subtract a couple of weeks to determine what your due date for multiples is likely to be. When you have a double pregnancy, babies are typically born a couple of weeks prior to the 40-week mark.

While technically, full-term for twins is the same as for singleton babies (39 weeks – 40 weeks, 6 days), 37 weeks is considered sufficiently full-term for twins. Twins are often born at 37 or 38 weeks instead of 40 weeks. To calculate when your babies will be born, use the calculator and then subtract two or three weeks to get a good estimate of the actual due date.

You may choose to have a more exact due date if you decide to deliver earlier than 40 weeks. Parents of twins or multiples often decide to schedule a C-section or induction instead of waiting for a natural birth. C-sections or inductions are usually scheduled at 37 or 38 weeks.

How is the date of conception for a pregnancy calculated?

For women with regular, predictable menstrual cycles, conception can typically be calculated as 11 to 21 days after the first day of their last menstrual period. Women typically don’t know exactly on which day conception occurs because they don’t know exactly when they ovulated. That’s why the conception date is calculated as an estimate determined by the first day of the last period.

How to calculate how far along you are in pregnancy?

This twin due date calculator can be very helpful in determining where you are in your pregnancy. However, if you’d like to do the math yourself, it’s fairly simple. To determine where you are in your pregnancy, count from the first day of your last menstrual period.

What's considered full-term for twins?

Twins are considered full-time at the same time as singletons, at 39 weeks. However, since most twins are born before the pregnancy due date, 37 weeks is typically considered full-term for twins.

Why are twins born earlier than singleton babies?

Twins are typically born earlier because a twin pregnancy has a high risk of preterm labor and premature birth. Some other conditions are also more likely in a pregnancy with multiples, such as preeclampsia, placental dysfunction, or twin-to-twin transfusion syndrome. These conditions often cause mothers of twins, triplets, and other multiples to have a preterm birth. Obstetricians and gynecologists may intervene by inducing or doing a C-section for the safety of mother and babies.

Is it better for twins to be born before 40 weeks?

There may be a good reason that twins tend to be born at around 37 weeks. At 37 weeks, babies have full lung capacity, so they should be born ready to leave the hospital in a couple of days. One study found that women who had an uncomplicated twin pregnancy who electively gave birth at 37 weeks had a reduced risk of bad outcomes for the baby.

When do babies need to be in the NICU?

Babies born before 37 weeks may not have well-developed lungs and therefore need more support to help them breathe until their lungs are sufficiently developed to breathe on their own. These babies often need to be in NICU. Generally, babies born between 32 and 34 weeks will likely not have long-term complications, but they often need to spend time in NICU as their lungs develop.

Why are twins so often induced or delivered via C-section?

Many mothers of multiples decide to have a natural birth, but others choose to be induced or have a C-section. Sometimes, it is safer for the baby and mother to choose when the baby will arrive. Prompting an early birth between 37 and 39 weeks may make a good outcome more likely. Some parents like the comfort of being at the hospital when labor begins or in order to have a C-section, especially if the pregnancy is high-risk.
