birth control
"I've been taking this since January of 2013 and it's been working great for me. I am not horribly incapacitated by my periods (before I would get really sick with bad cramps and nausea and headaches). My periods last maybe a day at most, no cramps, no usual symptoms like before. The smell of my periods has changed though I noticed, I'm not sure what to make of it.
Not sure if it's a side effect, but I've noticed I've become rather sensitive to the smell and taste of seafood. It makes me nauseous. That's pretty much the only 'side effect' I've noticed out of the normal."
