Mothers with a history of mental health issues should also talk to their doctor about it early in the pregnancy to help with possible depressive symptoms. Signs and symptoms
Antenatal depression is classified based on a womans symptoms. During pregnancy, a lot of changes to mood, memory, eating habits, and sleep are common. When these common traits become severe, and begin to alter ones day-to-day life, that is when it is considered to be antenatal depression. Symptoms of antenatal depression are:

Inability to concentrate. Overwhelming anxiety and fear. Difficulty remembering. Feeling emotionally numb. Extreme irritability. Sleeping too much or not enough, or restless sleep. Extreme or unending fatigue. Desire to over eat, or not eat at all. Weight loss/gain unrelated to pregnancy. Loss of interest in sex. A sense of dread about everything, including the pregnancy. Feelings of failure, or guilt. Persistent sadness. Thoughts of suicide, or death.Other symptoms can include the inability to get excited about the pregnancy, and/or baby, a feeling of disconnection with the baby, and an inability to form/feel a bond with the developing baby. This can drastically affect the relationship between the mother and the baby, and can drastically affect the mothers capacity for self-care. Such inadequacies can lead to even greater risk factors for the mother. Antenatal depression can be triggered by various causes, including relationship problems, family or personal history of depression, infertility, previous pregnancy loss, complications in pregnancy, and a history of abuse or trauma. Onset and duration of symptoms
Antenatal depression can be caused by many factors.
Antenatal depression, also known as prenatal or perinatal depression, is a form of clinical depression that can affect a woman during pregnancy, and can be a precursor to postpartum depression if not properly treated. It is estimated that 7% to 20% of pregnant women are affected by this condition. Any form of prenatal stress felt by the mother can have negative effects on various aspects of fetal development, which can cause harm to the mother and child. Even after birth, a child born from a depressed or stressed mother feels the affects. The child is less active and can also experience emotional distress. Antenatal depression can be caused by the stress and worry that pregnancy can bring, but at a more severe level. Other triggers include unplanned pregnancy, difficulty becoming pregnant, history of abuse, and economic or family situations.Commonly, symptoms involve how the patient views herself, how she feels about going through such a life changing event, the restrictions on the mothers lifestyle that motherhood will place, or how the partner or family feel about the baby. Pregnancy places significant strain on a womans body, so stress, mood swings, sadness, irritability, pain, and memory changes are to be expected. Left untreated, antenatal depression can be extremely dangerous for the health of the mother and the baby. It is highly recommended that mothers who feel they are experiencing antenatal depression have a discussion about it with their health care provider.
