I need help, can anybody please awnser my question?

Patient: What’s the chances of pregnancy if a guy gets off inside of you on the last day of your period? My period lasted six days, I became fertile on my seventh day. I ovulated six days after my period. Then the guy got off on my last fertile day, which was five days after I ovulate. Can there be a high chance of pregnancy? I’ve not bee on birth control in months and I’m not taking any kind of medicine.

Symptoms: Lower back pain, tiredness, sense of smell
