Constant headaches after mc

I wake up every morning with a migraine or headache and nauseous. I always been having horrible nightmares. It's to the point where I am either exhausted from waking up all night or I can't move for about an hour after waking up because I am so sick. My d&c was a month ago and my hcg levels are back to normal so I don't know if this is normal or if I should see my dr again. I mentioned it to her at my follow up and she seemed to think it was normal. I have a history of migraines, but l only a couple times a month.
