Thank you for your query at DoctorSpring.com
No, there is no way pregnancy could have occurred in the situation you mentioned.
For pregnancy to occur, intercourse is mandatory with ejaculation inside the female vagina.
There is no other possible way of getting pregnant.
Feel free to discuss further,

Thank you for the response. I guess ultimately what I was concerned about was if there was some small insertion of the toilet paper when wiping. Nothing other than the labia/lower vulva. But if that was a possible way to introduce semen enough for pregnancy to occur.
No even if it went in the semen has to reach the uterus, which it does only when there is penile insertion.
So please do not worry.
