headache constant everyday for more the two months

ive had a headache i remember the exact day it came on this year may 19th and it hasnt gone away its been about two months ive tried everything possible the first couple weeks it was like full on constant then i thought it started getting better but it seems to just get worse at nighttime now after midnight its like a throbbing tightening headache its still there in the day like a dull ache , i do have jaw clicking, locking and i also have low iron but im just not sure if these are the reasons as ive tried a night guard in my mouth and iron tablets ive tried so many things to relieve the headache but nothing helps its not like the headache is severe but its bothering me so much since its been so long with dealing with it and its caused me so much anxiety because i always think the worst and i just hope nothing is wrong with me does anyone know what this could be? i am 18 female by the way
