• Electrolyte disturbances (sodium, potassium, others)
• Blood clots in large vessels, usually in the legs
• Kidney failure
• Twisting of an ovary (ovarian torsion)
• Rupture of a cyst in an ovary, which can lead to serious bleeding
• Breathing problems
• Pregnancy loss from miscarriage or termination because of complications
• Rarely, death
