Hello dear I understand your concern There is no chance of the pregnancy. To become pregnant, full penetrative sexual intercourse or penetration upto vaginal intoitus with or without ejaculation in the fertile phase of the period is require. You did not mention about the period date and when you did the sex. Sperm can not pass through the cloth in to the vagina. So rubbing with part of semen does not cause pregnancy. Avoid stress, take healthy diet, drink plenty of water, do regualr exercise and maintain proper pelvic hygiene Use condom in future to prevent the unwanted pregnancy. Hope this may help you Contact HCM for further health query Best regards Dr. Sagar
