Me and my girlfriend had an encounter on 31 December 2019. We used a condom and there was no penetration atall. She touched me over the condom and then touched herself. When I ejaculated, she was wearing 2 layers of clothes. She was expecting her period on 4-01-20 but it got delayed and she got it on 19-01-20. It was painful and the flow was heavy and lasted 4 days like her regular period. She is experiencing fever and nausea right now. I am not able to get the fear out of my mind even though there is no chance. Can she still be pregnant?
