Ha when I was younger I called it "the curse". I try to ignore it, otherwise I feel like crap and usually get depressive about "being born in a freaking girl body". Sometimes I can't leave the bed/bathroom at all due to cramps/etc, so take Pamprin. Protection wise, it's easier for me to ignore pads. Conclusion is I'm miserable and probably not moving around much. Although I want to eat crap, eating less salty/junk food beforehand helps with my side affects. I've read that different foods can affect how periods go, so you could look into that and see if that helps.
For clothes, I tend to stay in a neutral catagory with a black t-shirt and dark pants. Even before bad dysphoria, I dressed this way. Hair wise, I like my short and shaggy hair. Having my mom force waist-long hair until I was 12, I'm never going back. I semi-wanted to try a half shaved look with shaggy hair on one side, but it would round out my face too much right now. For makeup, I used to wear a lot of black eyeliner/eye shadow/nail polish through school (none now). If I was born genetically male, I would probably still like eyeliner, but am opposed to it now.
On a slightly off note, when I was 15 my mom made me wear a dress for something, so I picked out a short black somewhat frilly dress. I ended up wearing an oversized black hoodie to cover it up for the event, but thought to myself that if I were a guy I would want to try it on at least once. If it wasn't for the fact that wearing a dress meant I was a girl to everyone else, it was fun to wear in a drag sort of way.
