Severe Headache

I'm 15 weeks and since yesterday have a really severe headache. I went to bed for an early night last night, I did sleep but had crazy dreams, and as soon as I opened my eyes this morning bam my headache was there. When I move my head it feels like my brain is banging off my skull and the light makes it worse. I am drinking fluids. Has anyone had this and/ or have any tips or tricks? I'd prefer not to take medication. Thanks
