HELP ! Is this normal ?

so today i woke up with a really bad headache.. i took a nap to forget about it but a little after i woked up its feeling worse, i feel nauseous, i get the chills then i get really really hot, & my bodys a little shaky. i cant stop crying at all & i dont even know why im crying in the first place. should i go to the hospital for this or is it just a migrane or pregnant stuff ?
