Help what is wrong with me??!!!

Kristie✨
I thought i had a miscarriage September 28th, went to er due to bleeding and bled for 4 days bright red. Now today i take a test figuring all hcg hormones would be gone and surprise, got a positive on the test. Could the hormones still be in my system, did i get pregnant again, or was i still pregnant? Please help any input is greatly appreciated. Ive been trying to get in with Dr, but no appt's till early November.???very confused
