I've been having a lot of problems with my birth control and missed about 3-4 pills during my ovulation cycle (or what I assume should be my oculation cycle). I went to my primary care doctor and he gave my ortho tricyclen. I'm worried because everything I've read says that ortho tricyclen should not be taken if you think you could be pregnant.

What are the chances I could be pregnant from missing a few pills and having intercourse during what could be my ovulation cycle?

Thank you!
