When to see a doctor?

I’m almost 15 weeks pregnant now. For the last several days or almost a week now, I’ve had constant headaches. They don’t go away. It’s a throbbing pain and worse than anything I’ve ever had before...

On top of that I developed a cold a few days ago. So now I feel super crummy.

When I went to my appointment Tuesday my blood pressure was normal. Should I still go to the doctor again?

I’m scared of getting preeclampsia...

Tylenol helps for a few minutes and sometimes doesn’t even help. It makes me want to just sit in a quiet room and not even talk. It’s the worst headache pain I’ve ever had.

Any ideas what I should do? Or should I see a doctor?
