... Sunday of my next period, I'm confused about what each different color pill does and I'm very concerned about the side effects, I haven't been able to find a lot of information or reviews on this pill. But it's my first birth control ever. My boyfriend and I have been together for three and a half years and haven't had sex before, so waiting a couple months before I get used to taking this is not a big deal. Can someone please give me an idea of what kind of common side effects there are, what the different colored pills do, when they will be effective, and any other helpful facts about TriNessa?
