Hello, I am a college student in a relationship, not ready for kids. I am on the pill as well. I had just finished my period from finishing the last pack, then started the new one just one day late, just finishing my period. I then caught up on my pills and had sex(with the withdrawal method, noted I do know this is not always the most reliable) about 4 days later. Do you think there is a chance I could have ovulated because of that day late starting pack? I am not overly concerned, just want to hear some outside feedback.
