What percentage of pregnancy losses occurs during the first three months?

The assertion that 80% of pregnancy losses occur during the first three months is grounded in statistical research surrounding early pregnancy loss, particularly miscarriages. Most of these losses occur during the first trimester, primarily before the 12-week mark.

This high percentage can be attributed to several factors, including chromosomal abnormalities in the embryo, hormonal imbalances, and maternal health issues that may not yet be identified. The first trimester is a critical period of development where many pregnancies do not progress due to various biological challenges.

By understanding that a significant majority of pregnancy losses happen during the earliest stage, healthcare providers can better support expectant mothers by offering appropriate care and information about what to expect throughout their pregnancy journey, particularly in addressing the emotional and psychological impacts of such losses.
