moldy weed-signs/symptoms?

um...i dont think i've been smoking moldy weed, but for some reason my dad does. i havent showed him any of the bud ive had cause he still isnt really chill with me smokin, its kinda like a "i'd rather ignore this and pretend its not there" type of situation...
anyways last friday - tuesday (the week before easter weekend) i had intense migraine, im talking mad throbbing, feelin the vein bulge at my temples, dizziness/nausia, and the occasional vomitting.. i dunno basically the worst headache i've ever felt. i havent cried in years and it bought me to tears. its like i can feel everysinge heartbeat in my temples and on the top of my head, the forehead, and the sides....
anyways, i've smoked a lot of bud, and many diff strands. this herb looked normal and i dont really suspect anything abnormal from it, but im just checking...my brother also had this disease last friday-monday, same symptoms and everything, but now he had a throat/cough thing going on. he smokes, but not much, and not often as opposed to me. i smoke daily, and often more than once-roughly 1/8-1/4 a week...
so to sum it up
does this seem like bad herb?
or
does anyone have a clue what i might have?
im going to the doctor tomorrow anyway, im just wondering if anyone has any insight they'd like to share
peace
