Miscarriage or false pregnancy?

I have had so many pregnancy symptoms like sensitive nose, nausea, cravings, endless hunger, and 9 days late and I’ve been way more emotional. But today I started spotting this really dark blood and I have cramps. It’s too soon to take a test because if I was or am pregnant I’d only be 3 weeks. I went to the dr but the hospital I live by can’t tell allergies from pink eye. And they told me I’ve been having all those symptoms because I was just really late on my period.
