I was on a birth control pill called ortho novum for only 3 months. It drove me nuts!! I am usually like easy going and stuff. When I was on that pill I was a totally different person. Like, just for an example, my boyfriend has like, a sort of family 'vacation home', and it's only like 20 minutes away from where we go to college. Well, one day when I was on that pill we were going to go out and spend the night and just have a good time. Well, when I got out there I was so moody and I had just convinced myself that I could not stay out there, so we had to leave. I don't really know if any of this is helping, but I have more... I never would have thought that this could have happened to anyone, until it happened to me. I was not myself, and I hated who I was. I was convinced that my boyfriend was cheating on me with random people, like my roommate who would never do something like that. I was just crazy. There was not a night those three months that I didn't cry. There was probably not a night that went by that I didn't scream at him over something silly, like where to eat, or going to his place. It was crazy. I called the doctor the day I was supposed to go in for my 3 month check up and told them I had to stop taking it. That was at the beginning of this year, and since then I have gotten on ortho tricyclen lo. I really like it, I am on my third month and I have not had any problems so far. Just normal emotions when I start my period or so forth, just cryey, but i've always been like that. I don't really know if any of this is going to help you or not, or if I have even answered your question, just felt like this was something I could share!! Hope this helps... :)
