Pregnant after mc / miscarriage

So on the 30th August I had a miscarriage which I think was a chemical pregnancy as when I went to the hospital they said this sounds like the bleed is now my period and all tests came back negative despite having a positive pregnancy test couple days prior. However my next period should have been due 27th September and now 11 days later my period still hasn’t arrived. I decided to take a cheap early pregnancy test this morning, could this still be pregnancy hormones from my prior mc or am I pregnant again?
