In the few weeks after giving birth, your hormones fluctuate, you aren’t getting enough sleep, and you are overwhelmed. You might feel teary, high levels of stress, tired and have mood swings. But with PPD, the symptoms are much more serious. Symptoms can begin shortly after childbirth or not start for several months. Your symptoms may include a change in appetite, fatigue, irritability, hopelessness, anxiety, insomnia and frequent crying.
