I just finished my 2nd pack of Femcon . For the first 3 or 4 weeks I had headaches and was nauseous often. The symptoms were more avoidable when I began taking the pill at night. I occasionally still woke feeling nauseous, but it didn't last long and soon ended. My breasts have gotten bigger as I now have trouble fitting into some of my bras. I am not complaining though, since I was a small B cup before. They are still tender and feel tougher. I also did notice I was getting some big zits (3 or 4 at once when I usually have 1, if any, a month) the first few weeks were hell, but I am glad I stuck it out. I know the side effects can really be miserable, but I encourage you to try and stick it out, for at least a month and definitely try, if you can, to take your pill a couple hours before bedtime so you can hopefully sleep through the unpleasantness.
good luck! (:
