What stage of pregnancy does the embryo split if there is twins?
In the case of non-identical twins, the two embryos are from completely different eggs and are quite independent of each other and so there is no splitting into two embryos. These are the most common type of twins.
With identical twins, it is the zygote that divides into two embryos, so you wouldn't say that the embryo divides. This usually occurs between 3-8 days after fertilization and the embryos will have one placenta and two amniotic sacs.
Sometimes it will occur before this time and each will have a placenta and a sac. Less frequently, the zygote will split up until 13 days post-conception with the embryos sharing a single sac and placenta. Complications are more likely in this case. Rarely, the split will occur after this, resulting in conjoined, or Siamese, twins.
