I take the ortho tri cyclen pill and I schedule myself to take them at 9:30pm everyday, one night I took it about 3hrs after scheduled time and the next night or 2 nights later I forgot to take it that night and took it when I woke up in morning approximately less than 15hrs after scheduled time. Then had sex a few days later. Am I okay? What are chances of pregnancy? Because I didn't think I missed a pill since I took them no later then 24hrs
