Symphysis Pubis Dysfunction (SPD): This condition is a common cause of pubic pain in pregnancy, occurring due to the relaxation of the ligaments and joints in the pelvis, which can lead to instability and pain in the symphysis pubis area. The hormonal changes and increased weight during pregnancy contribute to its development.

Round Ligament Pain: As the uterus expands, the round ligaments stretch, causing pain in the lower abdomen and pelvis, which can radiate to the pubic area.
Braxton Hicks Contractions: These practice contractions can cause discomfort and pain in the abdomen and pelvis, including the pubic area, especially in the later stages of pregnancy.
Urinary Tract Infections (UTIs): UTIs are common during pregnancy and can cause pain in the pubic area, along with other symptoms like dysuria and frequent urination.
Musculoskeletal Strain: The increased weight and altered posture during pregnancy can put strain on the muscles and joints, leading to pain in the pubic area.

Placental Abruption: Although less common, placental abruption can cause severe abdominal and pelvic pain, including the pubic area, and is a medical emergency.
Preterm Labor: Pain in the pubic area can be a symptom of preterm labor, which requires immediate medical attention to prevent complications.
Ovarian Torsion: This rare but serious condition can cause severe pelvic pain, including the pubic area, and requires prompt surgical intervention.

Pubic Bone Osteonecrosis: A rare condition where the blood supply to the pubic bone is compromised, leading to necrosis and pain.
Pregnancy-Related Osteoporosis: Although rare, osteoporosis can occur during pregnancy, leading to an increased risk of fractures, including in the pubic bone.
Pelvic Girdle Tumor: Tumors in the pelvic girdle, such as osteosarcoma or chondrosarcoma, can cause pubic pain but are extremely rare in pregnancy.
