Actually you are all wrong. One placenta = one chorion = monochorionic. All monochorionic twins are identical. Monochorionic twins have either 2 amniotic sacs = diamniotic (most common) or 1 amniotic sac = monoamniotic (rare). 70% of identical twins are either mo/di or mo/mo. The other 30% are dichornionic = 2 placentas, diamniotic = 2 amniotic sacs. With di/di twins, you will not know if they are identical or fraternal until birth, unless of course they are different genders. The ultrasound pic here shows di/di twins as you can see a thick dividing membrane that indicates 2 placentas.

Even if your babies have their own sac and own placentas, they can still be identical. It all depends when the egg split. You would hope for separate sacs and placentas b/c it's safer. I'm having two girls. They have separate sacs, but share a placenta. I won't know if they are identical until they are born. If they were in the same sac, then for sure we would have known that they are identical right off the bat. But since they are the same sex, the only way to know 100% for sure, is to test them when they are born.
