Positive test hours later?

My last period was April 15th. I am irregular but usually never over two months. I took a test on June 22nd and the control spot was blank. I threw it away and like 7 hours went by and I glanced in the trash and it was positive. I took two more but they were negative. I feel pregnant. I'm getting hormonal acne, back pain, I'm bloating, and I get nauseous after I eat. I can't go see a doctor til next week and I'm dying to know what everyone thinks. Thanks
