Miscarried… Could I be pregnant again?

I had a miscarriage Nov 17th. 6 weeks pregnant. Went to the hospital they sent me home and told me i’m most likely miscarrying and to follow up with OB. I bled for about a week and it wasn’t painful. If I hadn’t known I was pregnant I would’ve just assumed it was my period. I had sex since then. pregnancy test are still positive. OB appointment is not until this coming week. could I be pregnant again? Or is just the HCG hormones are still in my body..
