anyone else ?

last moth i had my “ period “ very very early and that’s never happened , it lasted 5 days and i didn’t cramp or anything & it was very light . i took a test but it was negative . i’m supposed to start my period in 3 days again .. usually a week before my period my boobs start getting super sore and tender but not this time ? this has never happened and i was spotting last week for 2 days , very very light . has anyone ever experienced this ?? if so what does it mean ??
