Help! Could I be pregnant

Last week my bf & I had unprotected sex about 3 days before ovulation & a fee times during. 3 days before ovulation after he finished he had some on his fingers and put a little in me. I’m 8dpo I’ve had cramps, nausea, food cravings, sensitive nipples, & tired a lot. Is it too early to test with my period being a week away?
