I'm having some horrid experience with femcon fe and going for my yearly tomorrow so i'm talking to my gyno about it then... but its DISTURBING me on how many girls keep saying "Tylenol is helping the head aches" i hate to be the bearer of bad news but Tylenol aka ACETOMETAPHINE DECREASES the effectiveness of femcon fe. Its different for EVERY birth control pill. IE: YAZ is decreased by everything BUT acetometaphine....
