Ultrasound can tell us a lot about a pregnancy, but it's not always perfect. This is particularly true in the early months. Though it is rare, it is possible to have a "hidden twin" who is not visible during early ultrasound screenings.

And while most women pregnant with twins or more will experience the same pregnancy symptoms as those pregnant with a singleton, they do often experience heightened pregnancy symptoms - severe nausea, extreme fatigue and fast weight gain - that may indicate that there are twins in their future.

During pregnancy, your body will go through a lot of changes and these changes will be more pronounced if you are pregnant with twins or multiple babies. Although at 5 weeks women don't know whether they are expecting twins or more, many women pregnant expecting twins or multiples suspect it from the start.

An ultrasound scan is the only way to confirm that you're pregnant with twins (McAslan Fraser nd, NICE 2011). The earliest you're likely to find out is between 10 weeks and 14 weeks, when you have your dating scan (McAslan Fraser nd, NHS 2019, NICE 2011). Ultrasound is almost foolproof at diagnosing twins.

Some women — including those with high-risk pregnancies or women carrying twins — have more scans. Ultrasounds have been used to monitor pregnancy for decades, and there's no meaningful evidence that they can cause harm to a developing fetus.

During twin pregnancies, it's possible — but rare — for one embryo to implant in the uterus while a second implants at an ectopic location, outside of the uterus. An ectopic pregnancy can be dangerous because when an embryo implants in a location other than the uterine wall, it's unable to develop normally.

Advances in ultrasound technology have reduced the occurrences of overlooking the second (or third) fetus. While a decade or more ago it may have been easier for a twin to "hide," today's imaging is far better and allows doctors and technicians to get a clearer view of the womb.

5: Spotting may be more common during twin pregnancies. "When you spot in the first trimester, you could be undergoing a miscarriage, and miscarriages are more common in mothers of twins, triplets, and quadruplets -- so we see more spotting in first trimester with multiples," Al-Khan says.

If you find that you're feeling extra, extra pregnant and believe that you might have twins on the way, there's really no substitute for an ultrasound to confirm that you're carrying multiple little ones. Increased hCG levels can be an indicator of a pregnancy that includes twins, but it's not conclusive evidence.

IUI itself isn't associated with an increased risk of a multiple pregnancy — twins, triplets or more. But, when coordinated with ovulation-inducing medications, the risk of a multiple pregnancy increases significantly.

Elevated Beta-hCG Levels You cannot conclusively distinguish a single pregnancy from twins on a urine pregnancy test. That said, you may have a very early positive pregnancy test if you are carrying twins.

In fact, most women carrying twins, triplets or more will go on to have uneventful pregnancies and healthy babies. However, there are conditions that can arise in any pregnancy, such as anaemia, preeclampsia or gestational diabetes, which are more common in multiple pregnancies and are therefore worth watching out for.

How Twin pregnancy can happen in IVF? However, it is possible to increase chances of twins with IVF even with one embryo, where one egg can split to form two zygotes. These are called monozygotic twins.

Twin pregnancies have a higher rate of miscarriage. In some cases, one twin may miscarry or simply "vanish," leaving a surviving twin. This is also known as Vanishing Twin Syndrome. Twins are at risk for intrauterine growth discordance, which is when one twin grows significantly slower than another.

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.

With careful listening, a doctor or midwife can sometimes detect multiple distinct heartbeats and might suspect that there are twins. If so, an ultrasound scan can provide confirmation. However, listening for heartbeats can be tricky and certainly not foolproof.

Obviously, the main difference between a twin pregnancy and a regular pregnancy is the presence of two fetuses. At the end of a twin pregnancy, a mother will give birth to two babies, rather than just one. The experience of a twin pregnancy can also be very different for some women.
