Doctor I Just Recently Had Sex With My Partner About

Doctor I just recently had sex with my partner about an hour ago and had protected sex, but after the sex I took off my condom and wiped myself down, after about 10 minutes or so I was all dried up and then she went down on me and we had oral sex for about another 10 minutes ..I was in the moment and had unprotected sex for about a minute or so until I realized I wasn't protected, could it be possible to have impregnated her with the dry sperm from before ? Or would it have gone away with the oral ?..
