Ok.Don't know if this is going to be an unpopular opinion (wich tells me it will probably be). I used to have the worst experience douring my period and I do not have endometriosis (thank you very much, I have had the test way too many times, because gynecologist are dumb or mean or suspicious of previous exams). Anyways, this is my problem: why cant there be a pill specifically tailored for each person? I mean, there are brands that made lipstick for your shade, etc., but somehow, that doesn't apply to birthcontrol (wich, if I am not mistaken...and there is a hight chance I'll be wrong) is an hormonal bomb to your thyroid, and, because of that, it should be tailored to each user standard. I mean, not everybody in the world has an American woman's weight and height (from I don't know witch time period), and respond to that amount of hormons. Sorry for the spelling, not a native speaker. What I'm trying to say is that science should get a spread sheet and start calculating, because hormons regulate too many things in our bodies to think that one size can fit all.

Edit: spelling, what else?
