Stressing!!

Hi all! I thought I’d just list some symptoms that have got me curious. I have PCOS, so it isn’t unusual for my period to be late, but it has been regular for more than 6 months now. This feels different. I have abdominal cramping and serious fatigue. I have what i thought might’ve been a yeast infection with itching and soreness with milky and white discharge. I have been feeling dizzy, and my moods have been extreme, I’ve been super sensitive and frustrated. (even for my regular PMS) my boobs have also been tender. The last symptom is CRAZY sex drive which isn’t usual for when my period is due. Like i can’t get enough even with the itching and soreness. (TMI i know). I am currently 8 days late for my period. I took a pregnancy test Thursday night with night urine, not morning and it was a clear negative. Any advice? Any similarities?? Sorry for the novel! Thank you in advance!!
