Weird pregnancy question

So this is a very awkward question in my opinion but I would like some outside advice. I have done a ton of research on the topic but figured this wouldn’t hurt. I am 21 years old and my boyfriend is 24 years old. We have been together for about 3 years so we are in an experimental stage to kind of spice things up a bit. Anyway, I was on birth control for about a year of our relationship and got off it about two years ago. Recently we have gotten drunk a few times and he has finished on my lower stomach then put his *** inside my vagina by fingering me. This has happened four or five times. This app said I was ovulating. What are the chances I could be pregnant? We are not exactly trying to conceive but we would not be unhappy with either result.

Thank you in advance for the input!
