Low hcg levels

Hi, im supposed to be 6 weeks an 3 days but last week started bleeding, when i went to the dr on friday a really straight an forward women came in the room said she would check my hcg levels , said sorry for your loss an walked out. My husband an i were both super confused, well monday came around an my hcg levels were back an only came in as a 8 , i was in shock since i still have pregnancy symptoms an i forgot to mention stopped bleeding on friday. Anyone else ever had this happen an still were pregnant, or does 8 always mean miscarriage?
