What is the percent of losing 2nd twin after 1 at 10 weeks?

The risk of losing a second twin after losing one at 10 weeks is around 5 to 15%. This risk varies depending on several factors, including the underlying cause of the first twin's loss, the health of the remaining twin, and the quality of prenatal care.

It's important to note that while the loss of one twin is devastating, the majority of women who experience this go on to have successful pregnancies and deliver healthy babies.
