Hello-
I am not sure if this is going to help you or not, but maybe it will.
I am not on this pill, I am taking trilevlen28, and it seems to be working great..No complaints. Anyways, here is what I found out on a website about that pill and bleeding.
Side effects of ortho tri-cyclen?
Side effects of ortho tri-cyclen, that may go away during treatment, include nausea, vomiting,

bleeding between menstrual periods, breast tenderness, or weight change. If they continue or are bothersome, check with your doctor. Check with your doctor as soon as possible if you experience persistent or recurrent abnormal vaginal bleeding, a missed menstrual period, dizziness or fainting, swelling of fingers or ankles, headache, or difficulty wearing contact lenses. Contact your doctor immediately if you experience sharp or crushing chest pain, sudden shortness of breath, sudden severe headache or leg pain, yellow skin or eyes, changes in vision, numbness of an arm or leg, or severe stomach pain. If you notice other effects not listed above, contact your doctor, nurse, or pharmacist.
-also on another site it mentions you will experience bleeding from the vagina if you have overdosed.
