TMI (af stuff, read in description)

Ariel
Past two months my period has been really weird. Last month it was three days late and I was kinda spotting before it started. Took a test and it was negative. This month my period started early. Instead of starting on the fifth I started on the 29th (I believe) and the first night and second day it was normal. Early but normal. Then the second night once I went to change out my pad it's like my period just stopped and was white discharge til about noon. Then I was bleeding like my cycle would end in a few days (best guess is 3) and then changed out my pad for the night again and it just stops. My first day I was cramping like normal and when I was pmsing my face broke out like normal. So idk what it could be. I'm just asking for some help because my period has never been like this and my fiance is the first and only person I have sex with.
