Aviane I have been on the pill for about a week now, I haven't noticed any mood swings but I have noticed the horrible cramps! I have had to miss work for these cramps, totally defeating the purpose of why I started this pill. I am stopping today! The stomach pain is un-bearable. I called the doctor and she told me that the cramps are a "normal" side effect of the pill. not worth it. not worth it at all. This is my first BC- im 22. Heads up ladies. Take all of these comments and seriously think before you use this pill.
