Is it possible for a woman to become pregnant if semen gets on her clothes during sexual activity over clothes, especially with her menstrual period being delayed?

One must repent to Allah Almighty for violating His sacred bounds by refraining from mixing with foreign women and looking at them, and by not touching them, as the Prophet, peace and blessings be upon him, said: "No man is alone with a woman except if she has a mahram (definition) with her," and as Allah Almighty said: {Tell the believing men to reduce [some] of their vision and guard their private parts}, and as the Prophet, peace and blessings be upon him, said: "For one of you to be stabbed in the head with an iron needle is better for him than to touch a woman who is not lawful to him."
