Am I just overly worried?

I went to the doctor 2 weeks ago so please dont say to go see one. Ive had migraine type headaches since the week of October 27th. Nausea, I'd say vomiting but its more like dry heaving nothing ever comes out. I was having fainting spells(thats why i went in after a week of all of this starting). Now its just dizzy spells. And blurry vision. They checked for swelling and checked my blood pressure and said both were fine. My next appt is November 25th. Yes Im well hydrated. All these things are still happening. Its been like 3-3.5weeks. the headache doesnt ever really go away.

Sorry this is so long. Has anyone started with these symptoms and ended up with preeclampsia? The Dr i was wasnt my normal but she said they would continue to monitor me like normal..
