This is an account of our monoamniotic pregnancy. A journey of faith.
Here we have a set of twins with two outer sacs (chorion) and two inner sacs (amnion). They are called dichorionic-diamniotic or di-di twins. This is your best case twin scenario, and typically this is what fraternal twins look like. They result from two ovum being fertilized by two sperm. However, identical twins could look like this if the single egg fertilized by a single sperm split very early on. In this case, the only way you would know for certain if the twins were NOT identical is if they are boy/girl twins (because yes, identical twins are ALWAYS girl/girl or boy/boy). Also, if the same sex twins look markedly different, you would assume they were fraternal. Sometimes it is not so easy to tell.
Here we have your typical identical twins. They have the same outer sac (or chorion) and two inner sacs (amnion). They are called monochorionic-diamniotic or mo-di twins. This is also a good scenario for twins, and we're still holding out hope that they will find a membrane (meaning two amnions) in our twins. These twins are always identical too.
