Any tips to battle the overwhelming headaches until I can get into the doctor?

I’m 11w6d. I have always battled headaches migraines and sinuses. I haven’t had any issues with headaches and migraines at all this pregnancy up until about 10 days ago. In the last 10 days I’ve had at least 20 headaches to the point where nothing is helping and I am stuck in bed all day. I have a doctors appointment on Wednesday to discuss with my doctor about how to go about taking care of them.

I’ve tried all my usual tricks between caffeine peppermint hot and cold packs on my four head Tylenol sleeping drinking water avoiding certain foods and nothing is helping. My first thought was maybe dehydration. But I drink over half my weight in water everyday.

Is there anything else I can try in the meantime until I get to the doctors because it’s starting to affect my every day life of me not being able to do anything.
