Please help - headache

Amy • Mom to 4 beautiful girls. 3/3/10, 4/27/14, 4/8/17, 3/7/19.

I’ve had a headache for 3 weeks now. I’m miserable. My doctor told me to try caffeine. That made it worse. I’m 34 weeks. The only thing that’s remotely touched if for whatever reason is Gatorade/Powerade 😭😭 I want it to go away.
