This NEVER happened!

So this morning I woke up with lots of cramps like if I was about to start my AF & my breast feel so sore! & tender D: so I'm like "okay I'm about to start, maybe next month is my month?" BTW (TTC) so I went to the RR & I noticed I was spotting, & well I was spotting just today for a while & now it went away...& my AF starts in 3 days which it needs to come this sat but it usually don't come early...so I'm kinda confused, so does this mean my period is coming or??? Idk I'm confused, I'm trying not to think (I'm pregnant) cause I don't want to keep my hopes high...
