Hands with semen

Patient: Me and my girlfriend were messings around. She gave me oral sex and i nutted. Afterwards, I pulled up her pants and so forth and she gave me another blow job playing with my penis as well. We said our goodbyes, hugged each other and kissed. she drove home and I did also. she played in her hair, applying grease, flat ironing also. She wiped her hands on her sheets. After about 40 minutes and then played with herself, immediately she stopped because she forgot she didn’t wash her hands and quickly did that. Could she be pregnant?
