I'm starting the pill ortho tri cyclen lo tonight. I've never been on birth control before so I'm not sure what to expect. It says to wait until either the first day of your period or the Sunday after your period starts to begin the pill. My period doesn't start for another eight days or so, but I called Planned Parenthood and they said I could start it earlier as long as I use condoms for the first month or so. Had anyone taken ortho tri cyclen lo? What should I expect?
