miscarriage question

Maret
Hoping someone out there has some insight for me... my Fiancée and I miscarried on Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>... I was 6 weeks and 3 days pregnant... I went to the doctor and she ran my HCG levels for 3 weeks... 10 days ago they were at a 0.5! My doctor called to tell me my miscarriage was behind me and that I was no longer considered pregnant...and today, I got a positive test... I'm not sure if it's still the miscarriage or maybe a new pregnancy... any help? I haven't had a period but my pregnancy signs are here...
