Pregnancy takes your mind and body through an ongoing stream of changes. On a basic level, your body is making unusual amounts of hormones. At certain times, this can make you feel exhausted, forgetful, or moody. On top of that, it is normal to be preoccupied with how your body is quickly changing, how to manage symptoms, how different your life is becoming, worry about the pregnancy going well, finances, and keeping up with everyday life.
It is common to go through many of the following changes in a pregnancy:
For some women, serious anxiety or depression problems improve during pregnancy. For others, they do not. If you find no pleasure in daily life, or suffer from a lot of sleeplessness (insomnia), sadness, tearfulness, anxiety, hopelessness, feelings of worthlessness and guilt, irritability, appetite change, or poor concentration, talk to your health professional. Without treatment, mental health problems can get in the way of a healthy pregnancy.
