This is my 3rd week on my first pack. I did not want to take bc, but had to since my insurance co would not cover mirena. I have noticed some indigestion and have gained 7 lbs in these 3 weeks. My appetite has changed, but I am working on trying to ignore the cravings. I am not sure if I want to stick it out for another few months or not. I can't afford to go out and buy new pants with my weight gain. Other than that I have not noticed any other side effects. I am anxious to see how this first period is going to be though.
