Can you have a miscarriage of one twin and not the other?

Can you miscarry twins at the same time?

Vanishing twin syndrome was first recognized in 1945. This occurs when a twin or multiple disappears in the uterus during pregnancy as a result of a miscarriage of one twin or multiple. The fetal tissue is absorbed by the other twin, multiple, placenta or the mother. This gives the appearance of a “vanishing twin.”

Result(s): Pregnancies with vanishing twins demonstrated a significantly lower mean 2-day percent increase in β-hCG level than singletons and twins (114.3% vs. 128.8% and 125.4%, respectively). Vanishing twins arresting at earlier developmental stages demonstrated significantly further reduced β-hCG level increases.

Why do most miscarriages happen at 7 weeks?
