I don't get it!

No bleeding what so ever, I'm now three days late for my SECOND cycle in a row. Positive pee tests, negative blood tests. My levels are a 2. I'm having so many symptoms. I am 8 weeks and 3 days, I FEEL pregnant. I wasn't even trying this last cycle as we just moved out of the state and were settling in. I don't know what to do. Am I crazy? I've posted so many tests on here that people said were positive! I'm so heartbroken. Can you still be pregnant but there be something wrong with my levels?? I don't have the money to see a dr, I paid $90 for the blood test and if I see a dr it's $180 to be seen and another $90 for the ultrasound. I'm so confused.
