Is there a possibility i might be pregnant?

i had sex 11 days after my last period.after a week and a half i've experience PMS-like symptoms(cravings,nausea,mild cramps,aversion to some odor,etc.)my supposed period was to come in a week.only it didn't come. now i'm 9 days late.the things i'm experiencing are tender breasts,clear white discharge,hot flashes,a little tiredness,cramps from time to time..:-(
