Do you ovulate while on the pill?

Brittany • 27. Finally got my BFP after 11 cycles of TTC by using the SMEP, Preseed, and a whole lot of prayers!!
I've read so many articles that say yes you do and so many that say no you don't. Does anyone know? I've been on the pill for 9 years and don't ever miss a pill. The Glow app says I'm ovulating but I'm confused if I really am. Can anyone help this confused girl out?!
