Combined pill and nausea or vomiting

I had several fortnight long periods on this pill. My regular periods are horrific so I was initially willing to take any side effects the pill had, and even though my regular level of pain/vomiting/fainting went away, I barely had rests from bleeding, my mood swings and hormonal breakdowns were uncontrollable, I gained a lot of weight, and I still had nausea and cramping. After over 18 months the side effects still had not dialled down so I had to quit.

My boobs have got so much bigger but my skin it completely cleared my awful awful acne and I have the clearest skin now.

This was prescribed to me to help regulate my periods; however did the complete opposite and have made them worse. I have no clue when my periods are going to begin or end now, as well as if the bleeding will be light spotting or extremely heavy. I have become incredibly sensitive to many things that would never have bothered me pre-pill, as well have been bed bound due to negative mood changes that I have no explanation for. I have been sad before, however, these feelings I could not explain or combat so I have decided to switch pill.
