I Have PCOS, Low Vitamin D. Since Getting On D

I have PCOS, low Vitamin D. Since getting on D supplements my period has been regulated, but now along with every cycle I get what seems like Tonislitius. I have been given antibiotics 4 times to no avail. Tested for strep, mono, STD's, thyroid, autoimmune and Lyme disease. All negative. It starts with a migraine (especially after working out) followed by light headedness, then a day or so later on the onset of my period coming my tonsils start to hurt, looks like I have oral thrush, tonsils begin to swell becomes difficult to swallow. I also have extreme fatigue, hot and cold sweats but no fever, body aches like I have the flu, and back of neck aches really bad, also trouble sleeping. Can this all be correlated with my period? I went years with no period and now I get it like clock work every 28-32 days. My medical office thinks I am a hypocrondriac thats over reacting they wont listen to me anymore. I'm fine the other 3 weeks of the month. Am I crazy?
