Unfortunately this is not the main concern of all parties involved in this, especially the big corporate pharma businesses have their own well being on the very top of their list.So every couple of years they launch a "new generation" of the birth control pills.
Which in it self isn't exactly bad yet. But what is worrying, is that although studies in Germany have found that these "new generations" of pills have a much higher risk of Thrombosis than older ones, the news are being pushed a lot more as the companies earn more on them.
So next time you go to your gyno, make sure you get a proper consult, that is actually in benefiting YOU and not the pharma industry.
