This is my first month on this pill and I hate it. It made me want to vomit and cramping the third and fourth week of taking it. On the days I took the brown pills, my cramps were even more painful and barely any bleeding. Just spotting. My gyno put me on this pill because I had irregular menstruation but I am also sexually active. We always use condoms though. Can I be pregnant? Help. What should I do?
