Ok...here is my story. I went on Loestrin 24 Fe at the beginning of August. My first couple weeks were ridiculous---so moody, constant cramping, bloating, etc. I gained at least 5 lbs in the first two weeks. I am very active and fit so this bothered me a lot. I thought about quitting BC altogether but I decided to switch to Yaz my second month. The adjustment wasn't perfect. I had some spotting...but my moods were sooo much more regulated and I FELT more normal. As I am in my third month now things seem normal. I have no spotting, my moods are normal, and I think I even lost some of the weight I first gained. They say it takes your body 3 months to regulate. I think that is true. I remember at the time of being on my first month, I didn't think I could make it. My advice is stick with BC...even if you have to change brands.
