I am switching back to my old birth control yaz after being on femcon for 2 months. I have gained a significant amount of weight and that right there is a big issue. I don't know why doctors are so pushy with this pill. I told my doctor when he prescribed it to me 2 months ago that i would rather go back on my old pill (yaz) and he said that he would like me to try this one out. I feel like there is some conspiracy with this pill. I hate it. i am so done with it as soon as i possibly can.
