Ovulation on Birth Control

Ashley
I made this account because I'm terrified of becoming pregnant. I am in no way prepared to take care of another form of life. My boyfriend and I are always very careful, but I keep trying to tell him that you do not ovulate while on birth control. Is this true? 
​I'm taking seasonique, a brith control with which I have a period every 3 months. 
​If anyone knows how this could affect possible ovulation and how to track it, or if there even is ovulation, that would be awesome. Thank you!
