What are the early signs of preeclampsia I should watch for?

The main warning signs are high blood pressure (especially if it's new or rises suddenly), protein in your urine, and persistent headaches that don't go away with rest. You might also notice swelling in your face, hands, or feet that shows up quickly, vision changes like blurriness or seeing spots, or upper abdominal pain. Any of these, particularly if they happen together, warrant a call to your doctor right away - preeclampsia can develop fast and needs medical attention, so don't wait it out or assume it's normal pregnancy discomfort.
