Pill/period advice

Girls, I stopped taking my pill in October 2017 as I wanted to have a period as I have always been on the pill with no break for about 8 years. Each month since then I would have really bad period pains which would make me sweat and almost faint however my periods were light and would only last approx 3 days. I've now decided to put myself back on my pill as I can't deal with the symptoms I get when having periods. I would have had a period 3 days ago ( if I had stayed off the pill) however I'm now not bleeding but still having pains as if im about to come on. I just needed some advice and wanted to know if anyone had experienced this before? TIA x
