Ovulation while on the pill?

Al

So I am on the pill and have been for over a year now. I take it same time every day no mistakes ever. Ive got an alarm on my phone and everything. My s/o and I use withdraw as our secondary form of protection. 2 months ago my pill dosage got increased a bit and around that time I noticed I started producing more CM than normal about 2 weeks post period.

Am I ovulating while on the pill?

I was under the impression while on the pill you do NOT ovulate because when I added birth control pill as my contraception method GLOW stopped telling me when I ovulate.
