Condom Slipped Off

Elysia

I was having sex as you do, my partner had already ejaculated maybe 30mins before, but the condom slipped off as his penis lost erect-ness (he did not ejaculate). I pulled the condom out pretty quickly with no semen in it and no semen seeping out of my vagina either.

Should I grab an EC as soon as i can? Or is the risk too minimal to even worry? I'm just very concerned. All help and info is appreciated!
