Looking for some opinions

OK so. For the past 4 weeks I've been sick (dizzy, headache, hot flashes, feeling like throwing up, cravings, cramps etc) even had a thick creamy discharge for 2 Weeks, but I had a period (I think). It was shorter and lighter then usual (only lasted 2, maybe 3 days). I am going to the doctor on the 31st but I was hoping for some insight... My boyfriend thinks I'm pregnant and is really Excited, while I'm trying not to be...
