birth control
"I've had three shots so far and loved it.  This is one of the only hormonal methods of bc that doesn't kill my sex drive or cause migraines. I tend to have one, two-week period per shot which isn't bad.  The first day or two after the shot is a little rough--I get hot flashes--but after that it evens out and you wouldn't even remember you've taken something.  I would definitely recommend that people try it at least once to see if their bodies tolerate it like mine does."
