If you are using a regular pregnancy test (not the super-sensitive variety) and get an immediate positive (especially a very dark positive indicator) a few days before your period is due, there may be an increased chance that you are carrying twins.
Do twins cause darker pregnancy test?
Here’s why: Home pregnancy tests look for the presence of human chorionic gonadotropin (hCG) in your urine, and levels of that hormone are indeed higher in multiple pregnancies — but not right away. It takes a few days for the hCG production of twins to outpace the hCG production of one baby.
Why is my pregnancy line so dark?
The linea nigra is the result of fluctuating hormones during pregnancy. One theory is that the hormones cause your body to produce larger amount of melanin (a compound responsible for giving your skin pigment), and this extra pigmentation shows up as a dark pregnancy line on your stomach.
Is twin pregnancy more painful?
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.
How early can twins be detected?
“Today, twins can usually be diagnosed as early as six to seven weeks of the pregnancy,” he adds.
Do twin pregnancies test positive earlier?
It takes about two weeks after conception for hCG levels to be high enough to be detected in urine using a home pregnancy test. In a multiple pregnancy, hCG levels can be higher than in a single pregnancy; plus, positive pregnancy tests can often be indicated sooner than in a single pregnancy.
Which parent carries the gene for twins?
This is why fraternal twins run in families. However, only women ovulate. So, the mother’s genes control this and the fathers don’t. This is why having a background of twins in the family matters only if it is on the mother’s side.
Can twins be detected at 6 weeks?
It’s possible to see twins (or more) on an ultrasound at around six weeks, though one baby may be missed at this early stage. Sometimes a heartbeat is seen in one sac, but not in the other. Rescanning in a week or two may reveal a second heartbeat, or the scan may show that one sac is growing and the other still empty.
What are chances of having twins?
Everyone has the same chance of having identical twins: about 1 in 250. Identical twins do not run in families. But there are some factors that make having non-identical twins more likely: non-identical twins are more common in some ethnic groups, with the highest rate among Nigerians and the lowest among Japanese.
