Diastasis recti, a widening of the abdominal muscles, is common during pregnancy and can cause back pain. Exercises and abdominal belts can help support the abdomen and align muscles as they return to normal. Postpartum depression affects some women within 4-6 weeks of birth, causing sleep issues, decision problems, and low self-confidence. Treatment includes seeing a doctor, eating well, sleeping, reducing stress, and talking to loved ones.
