Pretty odd experience

So I’m not one to take plan b because I usually am on bc but since it affects my anxiety and depression so bad I had to get off of it. When I first took a plan b it was three years ago and that was just because I was super paranoid but two days later I remember bleeding and cramping and that lasted for two weeks. Now earlier of this month I want to say the 9th I had unprotected sex and it was the first time my partner ever finished in me so I took a plan b the next day and I didn’t experience any side effects but my period did come a day earlier but I only bled for two days which is weird because I usually bleed for three/four days. I know there’s a high chance the pill worked but what are your thoughts? I don’t think I will test because I don’t have any pregnancy symptoms just abdominal pain. It’s been about two weeks since then so maybe I just haven’t really noticed any pregnancy symptoms? Either way if I am it is what is and I’ll be happy with whatever result. 😊
