I'm confused

Kimberly
Last month this time I was on my period or at least having cramps letting me know it was coming. This month I haven't had those cramps, I've had lower back pain, very vivid dreams, my nipples have become a little darker and my areolas are a tad bit scabby. No clue what this means. Also my fiancé ate some chips I really love but when I smell them and his breath I almost threw up.
