A miscarriage is the loss of a pregnancy before the 20th week. It often occurs when the fetus is not developing properly, which can be due to various factors such as genetic issues, hormonal imbalances, or health problems in the mother. Symptoms may include bleeding, cramping, and the passing of tissue. Most miscarriages happen in the first trimester and are usually not caused by anything the mother did. While experiencing a miscarriage can be emotionally challenging, it is a common occurrence, affecting about 10-20% of known pregnancies. Support from healthcare providers and loved ones can be helpful during this time.
