positive test before first cycle?

Kayla
I had a Miscarriage starting on March 6th 2017 bled for a week and a half and returned back to normal, but have never got a period. Is it possible to still be getting a positive pregnancy test from my miscarriage hcg levels?  Today is April 5th 2017, so pretty much a month later.This is the first test I have took since the miscarriage. And I'm not sure if my levels have gone back done bellow 5 or not they just called me and told me they were going down. I'm so confused. Thanks in advance.
