Out of curiosity can you get pregnant from pre-cum?

Potentially yes. Most studies have shown low levels of sperm or no sperm in pre-ejaculate with sperm not being motile (however, don't know how promptly samples were examined). One small study published in 2011 showed that there are some individuals with a high motile sperm count in pre-ejaculate. See: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3564677/
Pre-ejaculate. Theoretically 'yes, ' conventional wisdom always said this, although scientifically no study of any kind has ever been reported to prove it (at least as of 2013.) So common sense says that if preventing pregnancy is your goal, all unprotected exposures are a risk.
