OK need you to help

Elia • My first pregnancy ended at 9 weeks my baby in my heart was taken out by a D&C. Now want to see what life has for my DH and me.
Well my period was 3 weeks late, I had been naseaous soar boobs sleepy, started spotting on Sunday been spotting on and off since then. My periods are normally really heavy. Started getting more nauseous today and dizzy still sleepy, I took a pregnancy test a few days ago it was light positive. Haven't taken one since then. I was spotting when I took the test. Dr said it is normal in early pregnancy but is it really normal I haven't taken a blood test.
