Ovulating while on BC patch!

Ladies!!! My fiancé and I would love to try for a baby, but I'm currently still on my BC patch. I am planning on taking it off I just would like to know about how long it takes to regulate my periods with taking it off and about how soon could I get pregnant.bI know every woman it different. I would just like to know everyone's opinion. And is it true I don't ovulate right now because I'm on BC?
