Hi, I was wondering if I'm having irregular periods or if this normal. My last three cycles were 35,30,and 28 days long. With my period lasting 4-3 days. I have been under a lot of stress for the past few months. But its been getting better. Anyways I was just wondering if the varying length in my cycles was normal or not. Thanks :) Oh another thing is is that I did come off birth control but that was back in October.
