Help!!!

I have had my period now for over 3 years now and I am worried because it still hasn’t settled down into a regular pattern... I skip months I have up to 3 periods in a month and I often end up in a significant amount of pain particularly in my lower back durning my period. Although I know this is normal, the pain is a lot worse than I think it should be as it often makes me cry, even after painkillers!

My mum has suggested going on the pill, but I am scared about the side effects. Would you recommend the pill? What are some of the side effects? Are there other ways of reducing pain and regulating my period?!

Thanks 🙃
