I stopped taking BCPills. What can I expect?

I got my spell last week, and be suppose to start new pack this ending Sunday, but I didn't. My period stopped yesterday. What can I expect since I did not verbs a new pack of pills this cycle? Good & Bad effects that will come about to my body/hormones/attitude. The only convert that I saw was that my time of year was unpredictable. The first month I almost go 40 days with out my time of year!
Whatever your natural PMS symtoms, and horomonal level your BC pills were treating or taking strictness of will return. you may gain or lose weight, acne, irribility..you know.
