For three days now my head has been hurting and I feel nauseous like with food poisoning, especially meat smells make me lose appetite. Today at the clinic doctor measured my blood pressure as 112/72 while it's always 90/60 for me. I also gave urine sample there, showed bilirubin and ketone bodies. In the end they called an ambulance and sent me to the hospital with a diagnosis of preeclampsia. At the hospital they checked my blood pressure again but the urine was clean. They sent me home. But the headaches don't go away, even went for a massage on the neck-thoracic zone. I'm 38 weeks pregnant. Has anyone experienced this? The baby
