The pill and fertile window

Hi,

So I have been on the pill for about 5 years now. Ik that it prevents pregnancy when used correctly. But do I have a fertile window and ovulate since I’ve been on it so long? I take it at the same time every day and I don’t miss pills. I have another period app called clue and it does not show the fertile window or ovulation at all due to I have been on the pill so long. I was wanting to know because my boyfriend and I got onto this topic earlier and I would like to have the correct answer.
