Yes. I have had two miscarriages, both at 8 to 9 weeks. The first one, everything came out as one. On the second one, I passed the fetus first then passed the placenta the next time I went to the toilet. The placenta is much bigger.
There are many blood vessels on the surface of the uterus which 'feed' the placenta. In the umbilical cord there are usually two arteries and one vein, the arteries taking deoxygenated blood from the fetus to the placenta and one vein taking oxygentated blood fron the placenta to the fetus. Occasionally there nmay be only a single umbilical artery which may be a sign of a kideny malformation in the fetus.
Identical twins may or may not share the same placenta . Identical twins develop when a fertilized egg splits. Depending on when the split occurs will determine if the twins share a placenta, with either one or two chorions and amnions, or if they each develop their own placentas.

They are dizygotic. Fraternal twins.
I am pretty sure because that is how my twins are at the moment that one placenta and two sacs mean identical twins more often than fraternal and more often identical if they are the same sex

The placenta attaches to the child by three blood vessels that make up the umbilical cord. The umbilical cord has three blood vessels one for oxygen and nutrients from the placenta to the baby and two arteries carry deoxygenated fetal blood from the baby back to the placenta.

The main function of placenta in pregnancy is to supply your baby with sufficient nourishment. Generally it is found to evaluate around one-sixth of your newborn's weight. Every minute during the pregnancy, approximately about 550 ml of blood gets pushed into the uterus to replace enough nutrients with the placenta for your baby.
