Now I am getting my period (heavily) in the middle of my pack of pills. This is very unusual for me. I am about two weeks into my second pack of pills (I have been on ortho tri cyclen lo for about two years) and just started to get my period. I got it for two weeks when I missed the last 4 pills but once I went back on the next pack, it went away. Help! Do I start a new pack? Do I continue with this one? What do I do?!
