Can I end up pregnant?

Hi guys!

So long story short, I just got off my bc (depo) a month ago. Me and my fiancé had an “accident” about 2 days ago. According to this app, I’m ovulating. I finally had time to go out and get a plan b and took it today. According to what I’ve researched, I can take a few months to a year to be able to conceive after getting off depo, but I’m so paranoid. How likely am I to get pregnant? Any personal stories and advice is appreciated!
