I neeed answers please help

So I’m really hoping I’m not pregnant again at this point I’m not on bc yet & me and my child’s father don’t use protection he pulls out but this time I know he pulled out but as he was still ejaculating he pushing me down on it I’m not sure if it touched at all but I did wipe it off front to back and I’m scared I rubbed it on the opening could I possibly be pregnant again or would I have to be OV ??
