Can u get pregnant if your father used a soap then after 15-20 minutes u wash your hand then your vagina with the same soap?

Many things possible: Many things are possible in this life. However, teen girls do not get pregnant by using the same soap that somebody else in the family uses. That does not happen in the normal course of bathroom events. It does not happen with soap, shampoo, conditioner, or anything else in the bathroom. Also, older teen girls usually have their personal shampoo, soap, and lots of conditioner.
