Back on the pill but still spotting, had sex anyways

Patient: So today I went back on birth control, ortho tricyclin low, after my menstrual cycle. I was still spotting a little today but decided to have sex anyways. I’ve been on this pill for 5 months now and never really miss a day. Is there a greater risk of pregnancy for me, or am I safe because I’m back on the pill?

Doctor:
