Could I still be pregnant, please read and comment

Ka

Is it possible for me to be 8 days late for af and still negative hpts? I should have had my period on September 23! I'm very emotional and my boobs are terribly sore larger and veins are definitely showing. I'm nauseous throughout the day. More often than not. I went to doctor today and they took a urine sample and sent it out to the lab. Keeping my fingers crossed but ready to give up on it already! Could I have ovulated late?
