Can I be pregnant

I was on birth control (combo pills)) for 2 years stopped for about 6months and then got the depo shot and didn’t get it again after the 3 months.

I recently had unprotected sex and took a plan B immediately after having sex (literally an hour after). I’m currently in ovulation/ fertile according to this app. What is the likely hood of me being pregnant.

I will obviously be getting on Birth control again since having a baby is not in my plans Rn.
