Gedarel 20/150 pill and period like cramps

Reduced my period pains massively. I used to get really really bad period pains before I got put on this pill, once I was put on it, I still got pains but nowhere near as bad as they were.

I started this pill to help with my hormonal acne that had come on when i was on a different pill so decided i needed a change. Everything was fine for the first week or so, I went abroad and accidentally missed a pill due to different timezones. I bled consistently for 3 weeks after missing one pill. My anxiety has been increased and i am extremely fatigued all the time. I have painful sex, due to hormonal changes and vaginal dryness. I am now coming off this pill for a week to bleed and then i am going back on the pill i was on previously.

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.
