If you had semen on your hands and you washed them a few times could you get yourself pregnant if you touched yourself after that?

Pregnancy: Unlikely especially if you washed with soap. Soap and water kill sperm.

Unlikely....: If you washed well before getting any semen in the neighborhood of your genitalia, you are probably ok. But a pregnancy scare is reason enough to get some more reliable birth control, e.g., birth control pills, or iud. See your doctor or visit planned parenthood, and get something reliable to keep you safe. Good luck. Lgromkomd.
