I masturbated some sperm was on my finger i cleaned it with cloths n after sometime i rub fingers on vagina can she get pregnant?

Cleaned = no worries: Pregnancies don't start from cleaned hands or cleaned fingers. Fresh swimming sperm and a good egg are needed. If still worried, a urine pregnancy test gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If a woman gets her normal regular period, then she is not pregnant, and a test is not needed.
