Hcg is increasing

Olivia

Guys, I’ve got miscarriaged like a month ago. I’ve got my first hcg test on October 30th and the result was 516. On November 12th, I tried to use the pregnancy test and I got positive and the Hcg is 590. I’m on my period now. Is that possible? Or my misscarriage is not overly clean yet? Thank you
