Plsee help

I went into labor this Saturday. Ever since I’ve been having severe headaches or migraines I’m not a person who gets them like ever. I dont really drink coffee or soda or any type of caffeine so none of that. I honestly don’t know what’s wrong with me. Does this has to do with anything with labor. Ived been like this ever since. I feel weak with no appetite pulses in the middle of my head head hurts constantly. The only way I’ll feel better is laying down but everytime I’m up or walking I get the sharp pain. I honestly just wanna go to the hospital. 😖 I’ve token so many pills for headaches and it doesn’t go away Idk what’s wrong with me
