Hello, Headache commonly occurs due to dehydration, take adequate amount of water and fluids. Sometimes, low blood pressure and hypoglycemia can also trigger headache. Make sure your vitals are normal. Take food in time so that your blood glucose level is normal. Take adequate rest and quality sleep at night. Lack of sleep triggers headache. Make sure your blood pressure is normal. After abortion you may have heavy bleeding with clots for a few days and spotting for several weeks. You are having abdominal pain with heavy bleeding since abortion you are advised to get clinically examined by a gynecologist to detect any perforation, polyp, fibroid or fetal or placental remains that are not yet cleared out or any other pathology that is causing bleeding. You will be accordingly managed and treated. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
