I'm so confused.

My doctor told me when my blood test was done that I'm pregnant, now she's saying she might not have read the test right. Some pregnancy tests were positive, some were negative. I'm currently missing my second period, but I also stopped my birth control in July, though I had my last period at the end of that month. This whole Maybe Baby Limbo thing is getting really old. My obgyn doctor appointment can't get here fast enough so I can talk to someone who knows what they're talking about. Sorry, just had to vent.
