NEED HELP

Okay I'm about a week late almost two... Took 2 hpt both came out BFN... And then I went to the doctor and took another pee stick test and that came out BFN... The doctor says I should wait two to three more weeks to tell whether or not I'm pregnant... I've been getting the symptoms like peeing every almost every hour, sleep more like 10-12 hours, nausea, and tender breast.., how long should I wait ?? Am I pregnant
