Had a 1 nightstand

So I broke up with my boyfriend because he was cheating on me I went on a dating app and picked someone to sleep with because it's been awhile. So I had sex with this guy I dont know how but he said 2 condoms slipped off when I checked myself I couldn't find them he checked and they magically appeared so I watched/helped him put the 3rd one on we are going at it and it breaks! Like wtf but now I'm kinda scared cause I ovulated around then he didnt cum in me but I didnt realize till now that I was ovulating around then, my period is supposed to be next week. And I didnt take plan b cause I had to take one a while ago because I was raped
