Condom getting lost?

I was having protected sex with my partner a few nights ago (two days before ovulation) and once he finished, we noticed that the condom was left hanging about half way inside of me, and half out. I noticed that my pants underneath me were completely soaked, which is not normal. I’ve never experienced squirting, could that be what the liquid was? Or did the condom spill out? I took a plan b the the next day as we are not wanting kids at the moment... but is there a high risk for pregnancy? So many questions. 🙄
