Hi Marie,
Pill for me! It doesn’t stop you having them, although I do know somebody very severely disabled by MS, whom I believe takes the pill continuously, to make life less difficult for both herself and carers, as she would have no chance of attending to her own sanitary arrangements.
But for those of us less disabled, it does at least keep them regular, and in my experience, shorter and lighter too.
For years before diagnosis, I’d just got used to the fact I had awful periods - I didn’t know I had MS, and they were actually playing havoc with that every month, which was why I was feeling so rubbish.
They had also come down to only three weeks apart, and were lasting a week, so I was literally getting only two “normal” weeks before starting again, and back to feeling lousy. 
As soon as I was diagnosed, I realised that whilst MS itself couldn’t be fixed, other minor health niggles that were adding to it probably could be, so I went to the doc’s and got the pill.
It took a couple of goes to find one that works properly for me. My doctor only wanted to put me on the mini-pill, because of my age (mid-forties, like you), so it’s not a very strong dose.
My body sometimes ignored the first type completely, and went ahead and did its own thing (ovulated, and produced a full normal cycle - thank God I wasn’t using it for birth control!)
The ones I’m on now (Microgynon) don’t produce quite such light and brief periods, so not as great in that respect, but do have the virtue that my body doesn’t seem to have learnt to override them yet! Not perfect, but still better than a really bad period, only two weeks after the last one finished.
