My girlfriend and I were dry humping. She is on the mini pill but took the first pill of her second pack more than 3 hours late the day we were dry humping. I was wearing compression shorts, basketball shorts, and she was wearing kind of thin leggings. I've spoken with an OB GYN nurse and she said it's definitely impossible, other pregnancy educators say it's next to impossible or basically impossible, and no one has ever seem to have heard of a case where it's actually happened before despite saying its "possible". Is sperm able to travel clothes at all in general? Is sperm able to travel through these clothes to get a girl pregnant? Is there even the slightest chance that she could get pregnant or is it a definite impossibility? If likely, how much so? She has regular periods and this took place day 6 of her cycle, with slight discharge of blood still ending her period.
