My bf used a condom and came as he was pulling out but we’re not sure if a tiny bit of the cum came out from the bottom of the condom (where the ring is) and onto the outer lips of my vagina. We couldn’t tell if it was his or if it was white discharge that came from me. According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> I was in the middle of the fertile window when this happened. I took plan b the morning after just in case but I’m still unsure.
