The physical and hormonal changes that occur in pregnancy can make it difficult to recognise signs and symptoms of depression and/or anxiety. Some symptoms that may be experienced include: anger and irritability; low mood, feeling numb, empty or miserable; increased crying or feeling close to tears; worry, fear and stress that continually interrupts your thoughts and interferes with your activities; persistent muscle tension, chest tightness or heart palpitations; difficulty relaxing and sleeping, and; panic attacks. Depression and/or anxiety may be a problem for you if the symptoms are persistent and lasting for more than two weeks, and are disrupting your life or are distressing.
