bad gyno?

i had a d&c; and hysteroscopy done and had light bleeding after for three days then it stopped. then i started bleeding heavy red blood. i went to the dr amd she gave me pills to stop it. it didn't stop got heavier, then i was having labor like pains and went to the after hours dr who sent me to er. i waited there for hours and they did a blood test for hemoglobin which came back negative. so they rang my gyno who said the bleeding was just my period back. i told them i feel nauseous, dizzy, weak and couldn't walk far but they sent me home. no one looked at any part of my body. wtf. the dr i went to the next day just agreed with the gyno and told me to rest. so today i saw a new dr who was shocked by this. he ordered a swab to check for infection and gave me a referal for a new gyno. so mad!
