I"m one week away from the 28th pill. I've had nothing but problems with this pill. Yes it is suppose to stop you from becoming pregnant but It stops me from even wanting to have sex. My boyfriend told me to tell you "I"m pissed off". I don't have a sex drive anymore, I can't have an orgasm!!!! it's horrible!!! I get headaches every other day, and pain behind my eyes as well. I've been on my period all month. Do not take this pill if you have one that is working for you. I will continue to use it until the third month, I"ve been told thats when your body will be use to it. I will give you an update and let you know how it goes.
