I started minastrin fe for an ovarian cyst. However midpack, for reasons too long to explain, I stopped taking it. I did a Sunday start with this pack which was 6 days into my cycle and we did not use any backup protection during the time I was taking it. I finished 12 days of the pack. 3 days after stopping i started my withdrawal bleed and have been bleeding lightly for 3 days now. Is there still a chance I could be pregnant or is the withdrawal bleed a sure sign I'm not? I am not sure if this makes a difference but during an ultrasound (done on the day I stopped taking my birth control) they found another cyst on my other ovary. The technician said it might be from ovulation.
