Other Signs You Are Carrying Twins
My Tummy look huge. Am I carrying twins?
You might be. However, the most common reason for a bigger than expected bump is that your conception date was earlier than you first thought.
Also, your bump will get bigger earlier on in your pregnancy if you’ve had a baby before, as your uterus (womb) and tummy muscles will have been stretched by your first pregnancy.
The first ultrasound scan (dating scan) will determine whether your due date is correct and will also tell you if you really are carrying twins.
How early will i know if I’m expecting twins?
You may suspect that you are having twins early on in your pregnancy. If perhaps you’ve gained a lot of weight, have a bump earlier than expected, or are experiencing nausea and vomiting (pregnancy sickness).
But take note, these signs and symptoms can be misleading, and none of them means for certain that you’re expecting twins.
Having an ultrasound scan is the only way to confirm twins, so it’s usual not to know you’re having twins until you have your first ultrasound scan (dating scan), which you’ll have between 10 weeks and 13 weeks plus six days of pregnancy. Ultrasound is almost foolproof at diagnosing twins, but the greater the number of babies, the less accurate it is at detecting how many babies there are.
If you’re pregnant as a result of a fertility treatment, or have experienced complications such as bleeding, you may have a scan early in your pregnancy. This will be at about six weeks, and will confirm the pregnancy.
It’s possible to see twins at this six-week stage, though one baby may be missed. It is also fairly common for twins to be conceived, but for only one to develop (vanishing twin syndrome).
