If I've missed it and it's already been said then I apologise: Do you just want contraceptive in pill form or would you be okay using other methods?
If you're okay with using other methods then you might want to research the nexplannon implant. I used to have the same symptoms as you so I ended up missing a lot of school so I know how bad it can be. I've had the implant for about 6 months now and while it takes a couple of months to settle it's been brilliant. After it settled, I've only had 2 periods and they only lasted a few days with none of my previous symptoms and not even any cramps. It did take about a month and a half to settle during which time I was almost constantly on but again no symptoms or cramps at all.
Prior warning though, it can take longer to settle but it seems to reduce if not remove cramps and pains.
Hope this can help
