Help!!!

So on August 19th I miscarried at 7 weeks.. My hcg levels were dropping fast. They were at 269 then 2 days later when I started miscarrying they dropped to 226. So I only bled and passed everything for 4 days and it was done my symptoms went away and I felt fine . recently ive been feeling like I got those symptoms back . I've been nasuas and tired . that's all no sore breasts or nothing so today I finally decided I take a test and got this!! What does this mean.. Am I pregnant again! Im scared nervous anxious and happy
