I'm almost 18, (on the 2nd of March 2013) and I'm going out to town on the 9/3/13, did anyone have any noticeable changes after taking this pill? Also how do I skip my period and can I skip it the first month? Did many people lose weight? I'm 174cm and 95kg. I have such a big complex about my weight. (although I've had 2 children)
