Possible chance of pregnancy

So I had sex with my fiancé the other night and he had already came twice in a condom but the third time he came the condom literally came off inside me after he came. I checked the condom and there was like barely any in there. (Because he already came twice before) I was like on the last day of my fertile window. Do I have a high chance of getting pregnant? (Currently not of birth control due to trying to find a method that doesn’t put my body through absolute hell)
