You can increase your chance of twins by taking clomiphene citrate (Clomid) and letrozole (Femara) are ovulation-stimulating medications.
Both of these medicines are often given in IUI cycles and may help the body produce multiple eggs that may release at the same time.
If two (or more) are fertilized and implant, twins are a possibility.
Twins can occur either when two separate eggs become fertilized in the womb or when a single fertilized egg splits into two embryos.
Having twins is more common now than it was in the past.
Identical twins can have the same eye color as the other twin.
In fact most identical twins almost always end up being born with the same eye color although some twins are born with different eye colors.
With twins you will usually gain around 35 pounds of additional weight.
With a single baby you typically gain around 25 lbs but the additional baby can add those lbs up to 5 to 10 more additional lbs.
Twins do sometimes fight in the mothers womb and even kick and hit each other in the womb.
However the twins are not actually hurt when they kick or hit each other as the amniotic fluid acts as a cushion to protect them.
Being pregnant with twins is harder than being pregnant with one baby as the extra baby that is the twin makes your belly grow bigger and can cause more stomach cramping, more back pain and even more sickness as a result of carrying the extra baby.
A hidden twin is pretty common and occurs in around 36 percent of twin pregnancies.
Hidden twins also occur in around half of multiple pregnancies, or pregnancies where a woman carries more than one baby.
When 1 twin dies in the mothers womb the tissue from the dead twin is mostly absorbed by the mother's body and also by the remaining twin.
If the twin dies in the second or third trimester, there are increased risks to the surviving fetus, including a higher rate of cerebral palsy.
When a twin dies after the embryonic period of gestation, the water within the twin's tissues, the amniotic fluid, and the placental tissue may be reabsorbed.
Twins can have different fathers but only fraternal twins can have different fathers because identical twins only form from a single, egg and sperm combination and because of this they cannot have different fathers.
Twins can be born years apart although it's rare for them to be born years apart.
Twins can be born a year apart or even a few years apart although twins being born in different years is as rare as 1 in 2 million but it's possible.
Most twins are born at the same time and within minutes of each other.
The pros of having twins are.
You have 2 kids at once.
The twins have each other to play with so there's no need for a playgroup unless you want to have one.
You can more easily escape awkward conversations with strangers.
You never have to worry about having nice things again.
You have tougher skin.
Knowing that you're only going to have to go through pregnancy once to end up with two children.
Enjoying the fun of choosing two baby names that fit together perfectly.
Being able to hold one baby in each arm while feeling a huge rush of love and pride.
It is expensive to have twins.
Not only is it expensive to have twins but it's also expensive to raise twins although it's no different than the cost of raising 2 kids.
Raising twins can cost as much as $300,000.00 to $400,000.00 by the time they reach 18 years of age.
The mother of the father of the twins carry the twin gene which is then passed down to the mother of the twin through the father.
Twins are now considered to be a blessing and are considered lucky although before twins used to be considered a curse and not lucky.
Twins are lucky and it's considered good luck to have twins.
In ancient times, the Yoruba viewed twins with suspicion, and sometimes sacrificed them.
Although now twins are considered lucky.
In contrast to the Western view, the firstborn twin is considered the younger of the two.
The Yoruba believe that the "senior" twin sent the younger one out first to scout the world.
Twins are not going extinct although the birthrate of twins is going down.
There's not as many twins being born now as there used to be but it's unlikely that twins will become fully extinct as twins are still being born but not as many twins are being born.
Having twins can be bad as being pregnant with twins or multiples puts the babies at more risk of developing birth defects such as heart defects, digestive system defects, bladder defects, congenital heart defects, cerebral palsy, spina bifida and other neural tube defects.
However most twins are born healthy and without any issue but having twins and multiple babies increases the risk of birth defects.
Being a twin can make you shorter although some twins are actually pretty tall or average height.
One twin may even be slightly shorter than than the other twin and some twins even are fatter and weigh more than the other twin as well.
If identical twins have a baby they won't have identical offspring or identical babies because the only way you get identical offspring or babies is when a fertilized egg splits into 2 cells.
It's when those identical cells grow into identical twins and you get the identical twins.
Boy and girl twins are called fraternal twins.
When a boy and girl are born as twins they are called fraternal twins and do not have the same DNA.
If boy and boy twins or girl and girl twins also known as same sex twins are born then they are called identical twins as they have the same DNA.
Identical twins share the same genomes and are always of the same sex.
In contrast, fraternal (dizygotic) twins result from the fertilization of two separate eggs with two different sperm during the same pregnancy.
Twins are harder to carry than a single baby although it's not all that hard to carry twins.
You may experience more cramping and some more back pain with twin pregnancy but for the most part it's not much different than carrying and giving birth to a single baby but you should be prepared to go through slightly more pain with twins.
Twin pregnancies are harder than a single non twin pregnancy with just one baby.
However having twins and going through a twin pregnancy is not much harder than just giving birth to one baby but the pain may be slightly more and of course you'll have to push out 2 babies instead of one and go through the pain the second time.
Carrying twins can be a bit harder on you than carrying one baby but it's not as hard as carrying triplets or more than 3 babies at a time.
Most women who do have twins do experience more cramps due to the uterus expanding fairly quickly.
Twin pregnancies are more painful and women who have twins tend to have more back pain more severe stomach cramping and even a more painful pregnancy in general when giving birth to twins.
Being pregnant with twins also carries a higher rate of maternal anemia and a higher rate of postpartum hemorrhage (bleeding) after delivery.
Some women who are pregnant with twins may even decide to abort one twin and keep the other twin alive if they are having complications or if they cannot take care of twins and only want one baby.
