Hey! Need Answers please ladies

I have no clue if this is the right group or not, there’s not really a “could I be pregnant” group. I was just wondering what is the possibility of this : this past Sunday was ovulation day and when I woke up I had minor/server cramping, went away though. Later that night me and my fiancé had unprotected sex with me on top, obviously he came inside me. What is the possibility of pregnancy?
