I have been tracking my cycle to an extent- not taking BBT or anything but just watching my period and tracking the length of time between. We want another baby but aren’t trying to make it stressful just want to have sex and let it happen on its own so we are having 100% unprotected sex.

According to Ovia I started my fertile window Sunday. My SO won’t be back until Friday morning. What are the odds of conceiving from the dates we had sex to me ovulating?
