My head is about to explode 😩

Trouper
I'm about 12 weeks and have been getting pretty bad headaches daily. They have nothing on today's. It hurts from my shoulders up and is making me nauseous. It feels like a sinus headache mixed with a tension headache mixed with a dehydration headache. (I'm definitely not dehydrated right now). I don't know what to do to get rid of it. I've tried eating. I've been drinking water all day. I took 500mg of Tylenol a few hours ago and my headache laughed. Please help me get rid of it!
