CONDOM STUCK INSIDE ME

My boyfriend and I were having sex and i was riding him until his dick slipped off and he told me to put it back in. I felt it and I obviously could tell the difference between his own dick with and without a condom! It wasn’t there! The first thing he said was it’s probably inside me but I couldn’t believe it and we kept looking around. After a while of looking for nothing I went to wash my hands and check and it was way inside of me. I grabbed it by the ring and pulled it out. I already ovulated because I track my CM and i’m close to AF due to milky and not stretchy CM. Should I be okay meaning I don’t need to take plan b? What else should I do?
