am i pregnant?

i had sex with a condom last thursday, he came inside me however he still had the condom on. i started taking the combined pill on the friday (the day after sex). it's now been 9 days since i had sex and 8 days since i started the pill. could i be pregnant? i feel nauseous, i'm getting mild cramps especially in the evenings and nights. i'm craving weird foods and my discharge is a bit strange. my nipples are maybe a bit darker. my period isn't supposed to be for another week so i can't take a pregnancy test either. please give me advice and help asap.
