During which trimester is the risk of miscarriage the highest?

The first trimester is when the risk of miscarriage is the highest, primarily due to the significant developmental changes occurring at this time. During the first 12 weeks of pregnancy, the embryo is undergoing critical stages of development, including the formation of vital organs and systems. This period is characterized by a higher likelihood of genetic abnormalities, hormonal imbalances, or issues with implantation, all of which can contribute to miscarriage.

Maternal factors, such as age, existing health conditions, and lifestyle choices, can also increase the risk during this early stage. While the risk of miscarriage decreases as the pregnancy progresses into the second and third trimesters, during the later stages of pregnancy, the primary concerns shift toward complications such as preterm labor and placental issues rather than miscarriage.

This understanding highlights the importance of early prenatal care, as it can assist in monitoring potential risks and providing support to the mother during this critical period of fetal development.
