Pregnancy symptoms but negative tests.

Okay so before you tell me to go to the doctor I don't have insurance and already have too many medical bills. I've gone through almost every symptoms for early pregnancy and took a test yesterday but it came up negative. I don't know what to do. I want to be pregnant but I'm trying not to get my hopes up. Any suggestions? If I still get another negative test in a few days I'll just go to the doctor but I'd like to try to avoid that as best as possible.
