Persistent headache?

How many days would you say classes as a constant headache?

I’ve had an awful migraine since yesterday and the pressure was so painful at the back of my head. I took a nap and it moved behind my right eye. I felt okay before I went to sleep but it’s back this morning and it’s a dull ache at the back of my head again 😳.

It hurts when I cough or do something sudden like a big sniffle.

I have a cold so I know it could be related to that but I also worry about my blood pressure! I’m 13 weeks pregnant.

Would you see your GP at this stage or leave it a few more days? I can’t take paracetamol I’ll just throw it up.
