Because these problems can only be detected by scans, it's especially important for moms to be that are expecting mono mono twins to be constantly monitored, to enable any situations that occur to be dealt with as best as possible.
Will Having Mo Mo Twins Affect Your Pregnancy?
You're already having twins, so your babies are likely to have a lower birth weight than single pregnancies. By itself this is nothing to worry about, but twins that share a placenta are even more likely to have a lower birth weight.
Premature delivery is also incredibly likely, as it is with all twins. You aren't more likely to have an early delivery than any other type of twin birth, but the chance of your twins being born very early, (generally before 32 weeks) is much higher, almost twice as high.
Your doctor will likely recommend that your twins are delivered before their recommended due date, and it's also a lot more likely that a caesarean section will be recommended, to aid in delivery and lower the possible risk of complications.
If a cord entanglement situation is discovered, it is possible that your doctor will recommend an extremely early delivery, potentially as early as 24 weeks, as cord entanglement is a major risk and this gives them the greatest chance of survival.
TTTS has also recently become treatable, using a technique called laser ablation that strategically severs smaller blood vessels in the placenta to balance the blood flow between your babies. Whilst this sounds scary, it increases the chance of both twins making it to full term from around 10% to almost 70%!
What Can You Do for Your Mono Mono Twins?
Carrying them isn't normally any different for the mother. It generally depends on the needs of your babies, and can change depending on differing situations.
The most significant change is the frequency of scans and other health and observation checks, which your doctor will perform to make sure that nothing major is happening that could threaten the well being of your babies.
In the worst cases, for example cord entanglement, it's possible that you could be hospitalized to give your doctor the ability to constantly monitor you, but this is only going to happen in the worst cases.
In general, just look after yourself as best you can and follow any advice your doctor gives you. Get adequate rest, eat healthy, try not to overexert yourself, and don't worry. Remember that you're in the best hands possible!
